I can’t imagine that there has ever been a time when photographers had more camera bag options than we do today. There are more manufacturers, styles and price points than one can count. From generic knockoffs to designer leather, there is a bag out there to carry your camera, lenses and accessories.

But what if you want to carry your camera and some other stuff you need through the day? Maybe you’re a traveler and you want to have a water bottle, a raincoat and some ibuprofen as you hike through Paris? Or what if you are a student who needs a computer, a few books and lunch for a day at school? Or what if you just want to carry your everyday things with you as well as your camera? Well, then your options are a little more limited.

Maybe you’re a traveler and you want to have a water bottle, a raincoat and some ibuprofen as you hike through Paris?

Pulling out dividers in a photo backpack to fit in books, wrapping the camera in a towel and stuffing it in a daypack, or strapping a small camera bag to your hiking pack are all DIY solutions that folks have tried and found unsatisfying. The few options on the market tended to be bulky, difficult to access and frequently under-delivered as far as understanding what non-photo gear someone would want to carry.

In 2015, Peak Design launched its Everyday Messenger on Kickstarter with the goal of creating a bag that would both carry camera gear and the everyday stuff that someone might need for a day of work, school, travel or just living life. Proving that there was a real need for a bag like this, the company hit its funding goal in a single day and would eventually be funded to the tune of $4.8 million from over 17,000 backers.

This led Peak Design to start a second Kickstarter in 2016 to fund a backpack design (along with a tote and sling) for those of us who understand that two straps carry weight better than one. Once again, the new designs were funded successfully and the Everyday Backpack in 20L and 30L sizes was released to the public.




The ultralight waxed Kodra synthetic canvas is DWR coated for weatherproofness and comes in a Charcoal gray with red stitching accents or a lighter Ash gray with blue stitching accents and tan leather touchpoints (handles, zipper pulls, etc).

In Use

Many times manufacturers make claims about the design of their products that feel overstated when you are actually using them. I have to say that, for the most part, the design of the Everyday Backpack works just as it was intended to. I took the 20L on a trip to Europe recently and beat the heck out of it – crammed it under airplane seats, stuffed it with groceries, soaked it in epic rainstorms. All the while, I was accessing my gear hundreds of times to take photos at every opportunity. I came away pretty impressed.

Unlike a majority of camera bags on the market, the Everyday Backpack doesn’t use a system of individual padded dividers to create compartments for your gear. Instead, it uses what Peak Design calls 'FlexFold' dividers. This is a system of full-width internal shelves that can be positioned in the bag. The shelves have the ability to fold out of the way to create larger spaces, they also have the ability to fold up and create subdivided spaces. The design is a little difficult to explain in words or photos and your best bet may to just watch this video.

I was surprised at how well these worked generally. I was able to shift from a mirrorless layout to an overnight bag for an unexpected trip and then back again in moments. There are limits, and if you have specific needs you’ll be re-velcroing the shelves as well as folding/unfolding them, but it’s really a clever design overall.

The three main drawbacks I noticed were that the folding subsections could 'unfold' if something heavy (such as a lens) was in an adjacent subsection. In addition, since the shelves and subsections are not 'sealed' in the way that a padded-divider backpack is, small items like lens caps tend to wander around the bag easily. Finally, this design is not one that will allow you to use every inch of the bag for gear in the way a traditional camera backpack would. The idea is to have your camera get in one part of the bag and other everyday items in another.

The Everyday Backpack has four access points. The top section uses a flap cover that is secured with Peak’s excellent MagLatch closure that allows easy blind one-handed operation. The MagLatch has multiple attachment points allowing the upper section to expand to carry bulky loads or tighten up to make the pack as small as possible.

Then there is a top access computer/tablet/flat-stuff section that sits against your back. The other two access points, the ones you will use most often to access your camera, are dual full-length zipper openings on either side of the bag. The idea is that you slip one shoulder strap off and swing the bag around in front of you horizontally to access your gear.

A very full 30L Everyday Backpack

Overall, access is very well done. I was impressed how the fullness of any one area of the bag doesn’t affect accessing of any other area. The top section can be stuffed with lunch and extra layers of clothing and you can still use the side access to grab your camera or change lenses. This is one of the most crucial aspects in making a successful 'everyday' design and it is where many bags fail. One thing to note, however, is that the drawback to this design is that one cannot lay the bag on the ground and flip it open to access every piece of equipment at once. If that is how you tend to work out of your backpacks, the Everyday Backpack may not be for you.

There are a lot of neat design aspects to the Everyday Backpack and it would make a long article much longer to list them all. So in no particular order, here are a few of my favorites. The weatherproof fabric and zippers held up to some truly torrential rainstorms. Built in external lashing straps allow for a surprising amount of useful external carry. I strapped everything from groceries to a jacket to sandy shoes to the outside of the pack. The external side pockets both hide the waistbelt and external lash straps and can hold a water bottle or tripod.

There are a ton of small pockets in the bag for batteries, pens, cords, passports and whatnot. This not only gives you a place for all the little things, but it keeps them from bouncing around the bag or getting crammed together in the bottom. Every strap and handle is done in 'seatbelt' material that is soft and strong.

Finally, and particularly important for some folks, there is little about this pack that looks like a camera bag. You may look like a tourist or a student with your daypack on, but nobody is going to peg you as walking around with thousands of dollars in camera gear on your back. At least not until you stop to take their picture.

What didn’t I like? As with any bag, even really good ones, I had a few nitpicks, but I stress that they were all pretty minor. The most significant one was that I thought the shoulder straps could have been better padded. While they are ergonomically curved and have a clever axial rotating attachment system, users may not be impressed if they are used to technical outdoor style pack straps.

While there is a waist belt, it isn’t padded and exists more for stability than for taking weight off of your shoulders.

That said, the straps weren’t uncomfortable, even on long days (and did seem to 'break in' after some use). I just feel like a bit more function instead of form could have served better in this area, especially for heavy loads and the 30L size. Likewise, while there is a waist belt, it isn’t padded and exists more for stability than for taking weight off of your shoulders. Good to have, but doesn’t carry much load.

Due to being somewhat narrow, a good thing when moving through crowds, and having a slightly rounded design, the Everyday Backpack doesn’t stand up on its bottom or side particularly well. This isn’t a serious fault, but it is worth remembering that it is likely to flop over when you set it down and that you shouldn’t leave any of the access points open lest things roll out (good advice for any bag, really).

The external side pockets are really useful for both water bottles and things like tripods. However, unless you have long arms, it may be difficult to reach that water bottle while the pack is on. It’s possible, but you end up feeling like a contortionist. Beyond that, anytime you have something in those side pockets, it becomes a lot more difficult to use the side access openings.

I’m a big believer in the idea that how we carry our gear is as important as the gear itself.

Finally, at $260, this is an expensive bag. While the market has expanded enough that there is nothing particularly unusual about a $260 bag these days, it can still be a difficult decision when a bag costs as much as a nice used prime lens. That said, I’m a big believer in the idea that how we carry our gear is as important as the gear itself. If you don’t enjoy using your bag, you won’t bring your camera. For me, this bag is worth the money.

20L vs 30L

The design of the 20L and the 30L backpacks are virtually identical. The 30L is just a bit, you know, bigger. How much bigger? Well, you can see the numbers published above, and you probably know that 30L is 50% larger by volume than 20L. But in the real world, I think I would put it like this…

The 20L is best for:

The 30L is best for:

These aren’t hard and fast rules, you can configure these bags in a lot of different ways to carry a lot of different things. But if someone was asking me which bag to get to use as an airline 'personal item', I’d have to say the 20L as it is right at (or very slightly over) the size limit for many airlines. If someone was telling me they just HAD to have their full-frame F2.8 zooms with them all day long, I’d point them to the 30L. The 30L is bigger on the back and makes squeezing through crowds tougher than the 20L. But if you thought you were going to grab a few groceries on the way home, you’d probably be happy that you had the 30L.

To be honest, if I had to recommend one, I would suggest the 20L. I believe that the smaller less conspicuous size fits more into the intended 'everyday' design. At 5’5 I’m shorter than average for a guy, and when I’ve got the 30L on there is no mistaking that I’m wearing a backpack. It’s not like the 20L disappears when I have it on, but it is less bulky and obvious and I find it easier to move through life because of its smaller volume.

You can, and perhaps should, chalk my 20L suggestion up to my body type, but it’s an opinion I have seen echoed by other photographers as well. If you can, try to see both packs side by side before you buy. If that’s not possible, there are some good YouTube videos that compare the two sizes.

What’s the bottom line?

It is hard not to come to the conclusion that the Peak Design Everyday Backpack is the best 'carry a camera and some other stuff' pack I have ever used. The flexible storage space, ease of access, non-photo storage options, tough construction and overall form factor come together in a package that is completely usable. It is a solid feeling bag that does what it is designed to do.

Now, nothing on this earth is perfect and the Everyday Backpack is no different. But aside from wishing that the straps were designed differently and acknowledging that the price-point is going to be off-putting for some, most of the rest of my complaints are minor at best. I would happily use this pack across town for the day or across the world for a month. If you are looking for a backpack that you can carry your camera gear along with the rest of your daily life I’m not sure how you would find anything better than the Everyday Backpack.

Video: Sony a9 falls short with Canon 300mm and 400mm lenses attached

Sports shooters considering Sony's speedy a9 have one major hurdle to overcome: glass. There's a dearth of long, fast primes available to Sony FE shooters, and it seems like using off-brand glass while you wait for Sony to catch up just isn't a great option.

In this video, photographer Dan Watson of Learning Cameras tried both the Sigma MC-11 and Metabones Mark IV lens adapters to test how well the a9 worked when attached to the Canon EF 300mm F2.8L and Canon EF 400mm F2.8L (both version 1**)

Watson mainly wanted to test the focusing capabilities, and unfortunately, the results were somewhat disappointing.

Before you dive into the video, it's worth pointing a few things out. Our own Rishi Sanyal has tested the focus capability of the a9 with adapted lens, and points out a couple of caveats to Watson's otherwise solid points:

First, the performance of far off-center AF points depends on the lens. While Watson is correct in pointing out that they don't perform well with long lenses (despite working astonishingly fast with Sony's own 100-400 F4.5-5.6), they do work well with shorter focal lengths (we've had success with a Sigma 85/1.4, Canon 35/1.4, 24-70/2.8, etc.). With these wider lenses, 'Wide' area mode will continue tracking subjects to the extremes of the frame.

Second, Sony A-mount lenses adapted with the LA-EA3 adapter do shoot at an impressive 10 fps with autofocus, something we confirmed with the 50/1.4 (as long as you've updated the firmware of the adapter).* With the Metabones and Sigma adapters though, as with all Sony FE bodies, only the L drive mode offers continuous focus. And it's actually only 2.5 fps, not the 5 fps Watson mentions (technically L is 3 fps, but it slows to 2-3 fps with continuous focus).

With that out of the way, Watson's video is a great resource for seeing how well (or not) the a9 performs when attached to the long, fast Canon primes sports shooters love. And while single-shot focus with central points is speedy and almost 100% accurate with long adapted lenses, the lack of true subject tracking (Lock-on AF modes) or continuous focus at speeds higher than ~2.5 fps (or in video) will probably be a deal breaker for many fast-action photographers.

Once you've lost the impressive high speed shooting advantages Sony baked into the a9, you might as well be shooting with any other camera. Moral of the story: stick to Sony glass and hope they keep churning out new lenses at break-neck pace.

You can watch the full demo for yourself up top. And if you're considering jumping ship from Canon to Sony, keep this information in mind – like all previous Sony bodies, you'll only have access to the a9's slowest continuous drive mode when you're adapting your own glass.

* We've not yet confirmed the performance of off-center points with long A-mount glass.

** Correction: The first version of this article claimed the lenses used were the 300mm F2.8L II and 400mm F2.8L II. They are, in fact, Version 1 of both these lenses. The text has been corrected to reflect this.

Lucid VR begins sales of its LucidCam 3D VR camera

Lucid VR has announced the general availability of the LucidCam, its 3D VR camera.

The LucidCam captures a 180º field of view, less than the spherical 360º field of view found on many consumer VR cameras, however it does so with binocular vision, creating a 3D VR experience with a sense of depth. If you want to capture a full 360º view, three LucidCams can be combined to do so.

The LucidCam was developed with the help of a crowdfunding campaign in 2015, and while it's just now becoming available, the wait appears to have had at least one side benefit: the camera's original specs called for 1080p resolution per eye, but the final product will ship with 4K cameras instead.

In addition to 4K binocular recording, the LucidCam also supports live streaming through Facebook, YouTube, and Lucid's own iOS and Android apps, so that you can share what you're doing with friends in 3D VR. The camera also features stereo audio, 32GB of internal storage as well as MicroSD card support, HDMI out, and 1.5 hour battery life.

For those of you in the in the Bay Area, Lucid will be touring around San Francisco on Friday, June 23 to give people a chance to experience the LucidCam in person. The company will begin taking orders for the $499 camera on June 26, with shipments expected to begin in early August. As a promotion, Lucid will be offering a 15% discount to anyone who orders a camera between June 26 and July 26.

LucidCam Launching into General Availability with Truck Tour of SF Landmarks

Lucid VR truck to tour SF landmarks on Friday, June 23 encouraging consumers to capture and share VR experiences with friends & family far away

Santa Clara, CA – June 21, 2017— Lucid VR is officially kicking off the general availability of its simple-to-use, pocket-size 3D VR camera, the LucidCam with a billboard truck touring photogenic San Francisco landmarks all day on Friday, June 23. View the itinerary here.

This launch tour aims at encouraging more consumers to tap into VR and bridge the distances to their loved ones by capturing and sharing experiences the same way they see them. Lucid CEO Han Jin’s vision--to create a technology that brings the world closer together through a true 3D VR camera, the LucidCam--started with a crowdfunding campaign two years ago and has now come to reality.

“It’s been an incredible journey to bring this product to life and to the masses, as initially all I wanted was to build one for myself which would capture and share my life with my grandmother in China,” said Jin. “LucidCam creates images and videos which let you for the first time see the world through someone else’s eyes as if you were really there. I want everyone to have such incredible superpowers.”

On tour day, the Lucid VR truck will visit top SF tourist sights. Anyone can follow the truck, take pictures and share them with #LucidCam for a chance to win a free VR camera. Complimentary VR viewers will be handed out at every stop. The Friday tour kicks off the one-month LucidCam preview sale which starts Monday, June 26, where the camera will be discounted 15 percent off the retail price and delivered as early as August 9, just two weeks after the campaign closes July 26.

LucidCam makes virtual reality content creation and livestreaming in 3D at very high resolutions easy, with a simple plug-n-play process flow. Consumers can create their own 3D VR without a computer or any additional processing requirements, making LucidCam an all-mobile experience for capturing, viewing, sharing and delivering immersive content either through Facebook/YouTube or Lucid’s iOS and Android app to anyone around the globe. With two lenses like your eyes and two microphones like your ears, LucidCam recreates a first-person experience, allowing people to feel like they are seeing the world through someone else’s eyes.

Exceeding the original specifications of the LucidCam crowdfunding campaign, the engineers at Lucid VR enhanced it and developed a robust 4K 3D VR camera with on-the-go VR content processing of pictures and videos, plus livestreaming capabilities. With the addition of Lucid’s viewing clip or phone case, you can create and view your own 3D VR anywhere with a click of a button.

The special LucidCam preview sale begins June 26, and includes a 15 percent discount off the retail price, with delivery as early as two weeks after the promotion ends. Retail availability of LucidCams begins in August, with thousands of units coming into the online and offline sales channels. For more information about LucidCam or to purchase the device, visit

Flexy Paw treat holder phone clip tantalizes pets for better photos

Taking a photo of a dog or cat can be difficult, but here to help is Flexy Paw, a smartphone attachment that dangles a treat above the device's camera. The treat serves as a lure to catch the animal's attention, giving photographers a chance to snap to a photo. Because the attachment clips to the phone, it can be connected to nearly any smartphone, and keeps the user's hands free to compose and take the photo.

The clip holding the pet treat is attached to a flexible armature, enabling the photographer to reposition it out of the camera's field of view, as well as move it to one side or the other for posing purposes. Once the photo is snapped, of course, the pet can then be rewarded with the treat.

Flexy Paw is being funded through Kickstarter by Paw Champ, which is seeking $39,000 in funds. Backers who pledge $16 or more will be rewarded with a single Flexy Paw unit, while $32 or more gets backers two units. Shipping to Kickstarter backers is expected to start in November 2017.

EyeEm Selects helps you find the best images in your camera roll for posting

EyeEm has rolled out an update to its mobile app for Android that brings the new EyeEm Selects feature. EyeEm Selects helps you find the best photos on your phone's storage by scanning your camera roll and then using computer vision to suggest photos to upload. Selection criteria is based on aesthetics. The algorithms picks images that are composed particularly well, have the best quality, or highest chance of selling on the EyeEm stock image platform.

EyeEm is already using advanced computer vision technology on its servers for scanning of images that have been uploaded to the service and determine their content, relevant keywords, and aesthetic quality. The app update means that some of those algorithms can now be run on your locally stored images before uploading them. Running the process locally means users save bandwidth and battery power and don't need to worry about any third parties seeing their images if they decide to not upload them.

Selects is integrated into the image uploader component of the app. Above the camera roll you'll now see thumbnails of the images suggested for upload. EyeEm says the feature also provides an easy way for finding hidden and long forgotten gems in the depth of your camera roll that weren't shared right after capture. Android users can download the updated EyeEm app from Google Play now. iOS users will have to wait a few weeks longer.

Tamron introduces 'ultra-telephoto' 18-400mm F3.5-6.3 zoom lens

Tamron has introduced what it is calling the 'world's first ultra-telephoto all-in-one zoom lens,' the 18-400mm F3.5-6.3 Di II VC HLD. The lens, designed for Canon and Nikon crop-sensor bodies, is equivalent to 29-640mm and 27-600mm, respectively.

Built-in Vibration Correction reduces shake by up to 2.5 stops, and the lens' HLD focus motor promises 'accurate and quiet' focusing, according to Tamron. The HLD motor also keeps the overall size of the lens down: It's 124mm/4.9in long and 79mm/3.1in in diameter. The lens has 7 circular aperture blades, a minimum subject distance of 0.45m/18in and is moisture-resistant. Nikon owners will be pleased to hear the the lens uses an electromagnetic diaphragm system.

The 18-400mm F3.5-6.3 will be available in late July for $649.

Dramatic extended range achieved by combining cutting-edge optical design and other new breakthrough technologies including a redesigned cam structure

18-400mm F/3.5-6.3 Di II VC HLD (Model B028)

June 23, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of the new 18-400mm F/3.5-6.3 Di II VC HLD (Model B028), the world’s first ultra-telephoto all-in-one zoom lens for APS-C DSLR cameras, which covers a focal length range of 18-400mm. Since the 1992 launch of its AF28-200mm F/3.8-5.6 Aspherical (Model 71D), Tamron has dominated the all-in-one zoom category and has produced many lenses that cover wide-angle to telephoto zoom ranges. Tamron has now developed an ultra-telephoto all-in-one zoom that extends to 400mm (35mm equivalent of 620mm) and a 22.2x zoom ratio. Packed in a light, compact body (4.8in./24.9oz.)2 is Tamron’s accumulated knowledge and experience for all-in-one zoom lenses, including the most advanced optical and mechanical designs, an HLD (High/Low torque modulated Drive) for the AF system and the Vibration Compensation system. Photographers can now enjoy wide-angle to ultra-telephoto photography using one lens, which is ideal for travel photography and eliminates the need to carry extra lenses. The new Model B028 lens enables photographing a wide variety of ultra-telephoto images including everyday casual scenes. The 18-400mm will be available in the U.S. at the end of July at $649.


  1. The world’s first3 ultra-telephoto all-in-one zoom lens to achieve 400mm telephoto

The new Model B028 is the world’s first lens for APS-C DSLR cameras that covers a focal length range of 18-400mm and achieves a zoom ratio of 22.2x. The focal length of 400mm on the telephoto end enables the capturing of ultra-telephoto pictures with the 35mm equivalent of 620mm angle of view. Now, with just this one lens, a photographer can readily enjoy the power of ultra-telephoto to bring distant subjects closer as well as the perspective-flattening effects that only extreme telephoto settings can achieve. This all-in-one zoom lens is ideal for travel and everyday shooting. It allows a photographer to switch from wide-angle to ultra-telephoto without changing lenses, making it faster and easier to capture a much wider range of subjects including travel scenes, wildlife, action sports, landscapes, cityscapes, portraits and food.

  1. Excellent image quality across the entire zoom range, from wide-angle to ultra-telephoto and macro

The optical construction of the B028 consists of 16 lens elements in 11 groups. The use of specialized glass elements such as LD (Low Dispersion) and aspherical lens elements effectively minimizes wide-ranging aberrations, including chromatic aberrations and distortion, thereby assuring outstanding image quality. Optimum power distribution among the individual lens element groups achieves both the optical performance and the compact size necessary for an ultra-telephoto all-in-one zoom lens that boasts 400mm focal length. Also, it enables tele-macro photography with a maximum magnification ratio of 1:2.9.

  1. Lightweight and compact design exhibits Tamron’s basic philosophy for all-in-one zoom lenses

Despite being an all-in-one zoom lens that achieves 400mm ultra-telephoto, Model B028 is light and compact with a total length of 4.8in. and a weight of 24.9oz.4 A new lens barrel design utilizing three-step extensions was developed to enable the necessary elongation to produce a 22.2x zoom ratio. Compared to the conventional approach, the division into a larger number of cams ensures comfortable operation and stability while zooming. Tamron’s philosophy for all-in-one zoom lenses is to allow each photographer to casually capture everyday photos with a lens of a practical size, and Model B028 fulfills this philosophy.

  1. HLD motor provides high-precision AF and enables compact lens construction

The AF drive system for Model B028 uses Tamron’s exclusive HLD (High/Low torque modulated Drive) motor. The power-saving HLD motor produces outstanding driving torque, and adjusts motor rotation from low to high speed to enable accurate and quiet focusing. The HLD motor takes up less space thanks to its small size and circular arc shape that allows the size of the lens to be reduced.

  1. Equipped with the Vibration Compensation system necessary for ultra-telephotography at 400mm

Despite its compact size, Model B028 is equipped with Tamron’s proprietary VC (Vibration Compensation) system, which effectively curbs camera shake under low light conditions (such as a dimly lit room or at dusk) and while taking ultra-telephoto pictures. This greatly expands opportunities for casual handheld shooting. The jitter-free stability of the viewfinder image allows for easier framing and enables the photographer to compose the subject quickly and comfortably.

  1. Electromagnetic diaphragm system now used also for Nikon-mount lenses

The electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses5. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

  1. User-friendly features for everyday comfortable use

With an eye toward active outdoor photography, Model B028 features Moisture-Resistant Construction to ensure worry-free shooting as well as confidence while shooting under adverse weather conditions. Also, the Zoom Lock mechanism prevents undesired movement of the lens barrel under its own weight when the camera is angled downward while walking.

  1. Compatible with TAP-in ConsoleTM, an optional accessory product

The optional TAP-in Console provides a USB connection to a personal computer, enabling the user to easily update the lens’s firmware as well as to customize features, including fine adjustments to the AF and VC.

  1. External design placing importance on functionality and ease of use

While inheriting the design that makes use of many organic curves and the delicately polished form down to fine details that characterize the SP lens series, the new Model B028 comes with a highly sophisticated design that also places a lot of importance on the lens’s functionality and ease of use, featuring an overall form that faithfully encompasses the internal structures within, a slim Luminous Gold brand ring and the switch shape design.

2017 Roundup: $1200-2000 interchangeable lens cameras: full-frame

Last updated: June 23, 2017

For those wanting to step up from entry-level to midrange ILCs, there are many things to consider, including the choice between a DSLR or mirrorless camera, what sensor size suits you best, how important video is to you, and of course the lens system.

While full-frame cameras typically offer superior low light image quality and more control over depth-of-field, crop-sensor cameras are extremely capable in their own right - and (usually) more compact and less costly.

We've split the $1200-2000 ILC marketplace into two segments - full-frame sensor cameras (discussed in this roundup) and crop-sensor (APS-C/Four Thirds) covered here.

This group of full-frame cameras is split right down the middle, with three DSLRs and three mirrorless models. Sony is, by far, the major player in the full-frame mirrorless market, with most of the other manufacturers sticking with DSLRs.

Here are the cameras we'll cover in this enthusiast full-frame roundup:

Playing a Super Mario Bros. level with Hololens is the best case for AR we've seen

Developer Abhishek Singh makes a compelling case for wearing a headset and looking silly – he created an augmented reality Super Mario Bros. level and played through it in New York's Central Park. Oh, and he dressed as Mario for the demo video below, which is the best thing ever.

Singh tells Upload VR that he had to re-think some of the game elements to make it playable on a human scale – Mario can jump much higher than any plumber we know. Of course, there would be some obvious challenges bringing a game like this to the masses. But we've got our fingers crossed for a future of virtual reality includes life-size Koopas and gold coins.

NASA orbiter snaps aerial photo of lonesome Mars Curiosity rover

No human photographer could capture this aerial photograph. That's because this image is literally out of this world – it was captured by NASA's Mars Reconnaissance Orbiter on June 5th, and shows the Mars Curiosity Rover as it traverses the red planet, approximately 241,500,000 miles away from where I sit typing this right now.

It's hard to spot, and you have to look really closely, but there's a small blue dot in the very middle of the photograph above. This closer crop might help:

There, amid the Martian landscape, you can actually see the Curiosity rover as it trekked along the northwestern flank of Mount Sharp, on its way to 'Vera Rubin Ridge.'

The photograph was taken by the NASA Mars Reconnaissance Orbiter using its High Resolution Imaging Science Experiment (HiRISE) camera, which captures a red band, blue -green band, and an infrared band, combining these together to form an RGB image. Because of this, the photograph is not a so-called 'true color' image, and the rover appears bluer than it actually is.

Oh, and if you're curious, you can actually see what Curiosity was seeing when this photo was captured. The rover was using its Mast Camera to shoot these photographs of the Martian landscape while its picture was taken.

No, you don't need a $100 permit to take snapshots in Laguna Beach
Photo by Don Graham. Licensed under CC 2.0

The city of Laguna Beach has cleared up some confusion about its photography permit policy. A broad interpretation of one of its two photography permits created a minor uproar recently, as many people took it to mean that the city was requiring a $100 permit for anyone taking photos. It seems now that this wasn't the intention.

As it stands, the city has two permits for two different types of photography: commercial and 'non-commercial'; the latter has a $50/hr rate with a minimum of two hours required. This meant, as the policy was interpreted, that anyone taking photos – including personal photos – in Laguna Beach were required to buy a $100 permit.

The non-commercial permit category's vague description resulted in quite a bit of public complaint, and the city has chosen to rename it as a result, leaving only talk about true commercial photography on its website's related permit page. The category was never intended to cover casual personal photography, according to a city official speaking to OC Weekly. Rather, the 'non-commercial' permit category was created as a cheaper alternative to the primary commercial permit, giving photographers an option for 'less complicated photo shoots such as engagement photos.'

The city's website still specifies two different photography permits, but one with a new name: commercial and 'professional still photo.' The latter carries the same $100/2hr minimum as the former 'non-commercial' category, explaining that this option is for 'single camera shoots such as engagement photos, wedding photos, family portraits, holiday cards, etc.' Nothing about the permit policy except the 'non-commercial' verbiage has changed. However, it is now clear that personal, non-compensated photography doesn't require a permit.

Caltech research team develops lensless camera
Image: Caltech

Smartphone cameras have improved considerably over the past few years but despite innovations such as image stacking and dual cameras with image fusion technology the cameras are still limited by the laws of physics. This becomes particularly evident when looking at the 'tele' lenses that have cropped up on some recent high-end smartphones with dual cameras, such as the iPhone 7 Plus or Xiaomi Mi6.

Due to space constraints in the slim smartphone bodies these lenses use smaller sensors and offer considerably slower apertures than their wide angle counterparts which makes them a lot less usable in lower light conditions. However, now it looks like a research team at Caltech could have found a solution to the problem. They have developed an 'optical phased array' chip that uses algorithms instead of a lens to focus the incoming light beam. A time delay which can be as short as a quadrillionth of a second, is added to the light captured at different locations on the chip. This allows for modifying focus without a lens.

Professor Ali Hajimiri says the system 'can switch from a fisheye to a telephoto lens instantaneously - with just a simple adjustment in the way the array receives light.' The existing 2D, lensless camera array consists of an 8x8 grid with 64 sensors and is capable of capturing a low resolution image of a barcode. The current image results are a long way from current smartphone cameras but at this point the system is only a proof of concept and potential commercial applications are a few years in the future. The team's next objective is to use larger receivers that are more sensitive and capable of capturing higher-resolution images.

Getting the shot: macro photos of paint and water that look like CGI

Vibrant colors of acrylic paint billow into clouds inside a water tank. © Photo by Alberto Seveso

Illustrator and photographer Alberto Seveso's paint photography is out of this world. His images – macro photos of billowing clouds of color – look like they were generated by an animation program. But as he tells DPReview, it's all very real.

The process itself, says Seveso, is quite easy: just pour varnish or acrylic colors into a water tank and take a burst of photos. Understanding exactly how to do that – what light you need, what works, and just as importantly, what doesn't work – is the time-consuming part.

'I spent a lot of time building all the stuff I use to shoot varnish into the water, and it’s still a work in progress,' Seveso tells DPReview. 'It’s very important to find the right light and, the hardest part, find the perfect mix between varnish and water and the way to pour this mix into the tank... not too fast not too slow.'

For his pictures, he uses either a Canon EOS 60D or Canon 7D Mark II with a Canon EF-S 60mm F2.8 macro lens attached. The tank is lit by either fluorescent light (personal projects) or higher quality tungsten Fresnel lights (for commercial assignments), two on either side of the tank, placed in front of either a black background or a softbox if he's shooting on white.

You can see the setup for yourself in the BTS shots below:

And here is a video Sony made to show off Seveso's paint work (and sell some phones and tablets while they're at it):

Seveso says he was inspired to create this kind of photography in 2009, when he saw 'something similar but classic,' probably ink drops in water.

'I realized there was more to explore, different materials to mix, so I started to experiment with different kinds of liquid like acrylic colors, different types of oils, sparkling water, gels, metallic colors, ice, food coloring, and other things,' he says. 'Over the years, I've tried to develop a personal approach to this technique, developing the project in a very personal way and trying to focus on the details.'

Translation: macro photography.

These close-up, colorful photographs have become Seveso's calling card. And what a gorgeous calling card they are.

Before we let Alberto go, we asked him one more question. Does he have any advice or tips for people who would like to try this kind of paint photography for themselves?

His answer?

'Practice,' he told us emphatically. 'It takes a lot of practice to understand the exact mix between liquids to get separate colors, details and color filaments - this is perhaps the hardest part.'

Facebook testing 'profile picture guard' feature that prevents sleazy photo theft

Facebook's new 'Profile Picture Guard' feature makes your profile photos much harder to steal. Photo courtesy of Facebook

Photo theft is a big problem on Facebook, and the social network is finally doing a little something to combat it. Starting with its users in India, the Silicon Valley company is testing a feature called 'Profile Picture Guard,' which prevents other people from saving or even taking a screenshot of your profile pic.

As the headline suggests, Profile Picture Guard is still in the testing phase. In fact, it's currently only available to users in India, the country that Facebook says inspired the feature.

'In our research with people and safety organizations in India, we’ve heard that some women choose not to share profile pictures that include their faces anywhere on the internet because they're concerned about what may happen to their photos,' explains Facebook. So they designed a little peace of mind.

Here's a look at how it works:

As you can see, the feature works in four ways. (1) It prevents people from saving, sharing, or (Android only for now) taking a screenshot of your photo. (2) It allows only you and your Facebook friends to tag the photo. (3) It adds a blue border and shield icon to your photo, indicating it's 'protected.' And (4) if you so choose, you can overlay a watermark design across the entire shot.

Combine all 4 deterrents, and its far less likely you'll find your profile pic on some random website. How much less likely? Facebook did some testing:

'Based on preliminary tests, we’ve learned that when someone adds an extra design layer to their profile picture, other people are at least 75% less likely to copy that picture.'

Facebook 'hopes' to expand the feature to other countries soon. For our part, we hope they expand its scope even sooner. Protecting your profile picture from saving, sharing, and screenshots is a great first step; however, for the photographers out there, this kind of universal feature for all of their photos at once – or perhaps available for individual albums – would be a game-changer.

The ease with which photo thieves can filch photos off of social media sites like Facebook is one of the main reasons photographers choose to stay away. Profile Picture Guard is a small step in the right direction; a broader Picture Guard would be a giant leap.

Now we know: Sony a9 is sharper than we thought

To make a long story short, we've re-shot our studio scene shots of the Sony a9 with the FE 85/1.8 lens, and they're much sharper. We apologize for misleading any of our readers, but it's a long story - see below. To jump to the images, just click the button, but we do encourage you to read the full text as well.

The Long Story

You may have noted on the studio scene page of our Sony a9 review that we admitted to having quite a bit of difficulty focusing the camera with the new Sony 85mm F1.8 lens in magnified live view. The maximum magnification (x9.4) on the camera LCD made it very difficult to fine tune the 85/1.8 precisely. Multiple AF-S attempts yielded shots varying slightly in sharpness, but this is not unique by any means to the a9: all cameras exhibit some tolerance when it comes to critical focus of a flat chart (which is why we always manually focus, and use a rail to fine tune). The only way to check focus on each shot was to shoot tethered and check each shot magnified on a monitor. Of course, every time we thought we'd nailed focus, we'd try nudging the camera or focus ring just a bit to make sure we couldn't do any better, and then realize we'd fallen off a bit.

And so the search began again and again, with the quest for perfect focus ending up a bit of a fool's errand. Electro-mechanically coupled focus elements also don't make things easier: often small turns do little to nothing, requiring coarse back and forth movements to 'hunt' visually for optimal focus. We finally tuned focus to what we thought was reasonable (we look for maximum aliasing in the central Siemens stars, and color aliasing in the text), and shot our entire studio and dynamic range tests.

Subsequently, we got lots of complaints about the a9 being soft.

The Lens Factor

Was it the lens? This is the first Sony FE camera we've shot without the stellar Zeiss 55mm F1.8. We've had a long-standing policy of shooting with an on-brand 85mm equivalent lens per-system, to maintain equal distance from camera to target, something that allows for all images to be rendered with equal perspective. With Sony's recent release of the razor sharp FE 85/1.8, we thought we'd stick to our policy and give it a try.

But we don't blindly switch lenses for a system; we first verify:

  1. The new lens is at least as sharp as the previous one.
  2. The lens transmission (also accounting for the aperture at F5.6) is not so different as to affect noise comparisons.

Our initial testing showed equivalent sharpness between the 55 and 85mm F1.8 lenses on even a high-resolution a7R II (see below). Furthermore, DXO verified similar levels of sharpness between the 85 and 55 F1.8 lenses (which both perform better than Sony's 85/1.4 GM, surprisingly). And while we don't have a way of directly measuring lens transmission, we measured signal:noise ratio of a few grey patches in our scene with the two lenses on the same camera body, and found them to be within 1/6 to 1/10 EV of one another. That meant the new lens would not make the a9 look better, or worse, in Raw noise comparisons compared to if we were to use the Zeiss 55mm F1.8 at F5.6.

Some Friendly Help

While plowing ahead with other aspects of the review, a message from forum expert Jack Hogan turned up in my inbox showing this:

Long-time forum member and all-round expert Jack Hogan did a quick MTF analysis per color channel based off of the slanted edges in our scene. Uh-oh. Looks like the red channel is focused better than the green channel, yielding a calculated MTF50 of only 945 line pairs per picture height.

Importantly, the green channel should have the highest MTF.

It was now clear that focus was the underlying issue with our studio shots. Not a bad lens. Not a strong anti-aliasing filter. But simply the fact that the lens was not optimally focused: if it were, the green channel would have the highest MTF.

So we sat down one day and spent the entire day shooting many, many runs of our studio scene, slowly moving a macro rail (rather than coarsely adjust focus on the lens) between each run. From these shots, we picked the (centrally) sharpest runs. While our copy of the 85/1.8 appears slightly decentered (the left is softer than the right), the results now are much more in line with where things should be:

Jack Hogan re-analyzed some of our new studio shots of the a9, and the green and blue channels now have the highest MTF, not the red channel. The calculated MTF50 of 1125 lp/ph, which is a 19% increase in linear resolution over our previous results.

A side benefit of analyzing properly focused shots is an ability to estimate the strength of the anti-aliasing filter, which appears to kick in around 0.744 cycles per pixel (the first minimum in the MTF curve). For comparison, the D5's anti-aliasing filter kicks in around 0.748 cycles per pixel according to Jack's analysis of our studio scene shots. Meaning the a9's AA filter is fairly typical.

Have a look at our updated images, and our updated image quality analysis based off of our new results:

Editor's note:

As camera sensor and lens resolutions are becoming astronomically high, tiny little differences become visible in pixel-peeping. And that's precisely what our studio scene allows you to do. Remember that even within the depth-of-field, there is a plane of peak sharpness.

Our studio scene isn't perfect, but it can be helpful. It has its caveats though. For example, because we don't control for lens transmission from brand-to-brand, or any shutter speed inaccuracies, we state that noise comparisons are only accurate to within 1/3 EV. Trying to extrapolate differences smaller than that from high ISO shots of our studio scene is meaningless: margins of error are real.

The same goes for sharpness. The reality of lenses and mounts is that there is copy variation - in both. Therefore, we urge you to make sharpness comparisons largely from the center of the scene, which removes the lens (as much as it can anyway) from the equation. The rest of the scene is useful for assessing color, detail retention and noise at high ISO in JPEG and Raw, respectively, and other subjective attributes. And keep in mind common sense things: the lock of hair is well above the plane of optimal focus, and different lenses can have field curvature which either helps or hurts the sharpness of this lock. It's important to keep these sorts of things in mind when pixel-peeping our scene.

This time, with the a9, we take full responsibility for a non-optimally-focused set of shots. But the process has also been a learning experience for us: depending on a lens' electromechanical coupling and the magnification of the live feed, it can be extremely difficult to take test shots that stand-up to the level of scrutiny our image comparison tool demands. And there are the practical issues mentioned above around taking one shot, checking it, and repeating the process - returning to the position of optimal focus is nearly impossible. The results of visually checking which shot is sharpest can even vary from tester to tester. I can assure you though: we are constantly working on methods to improve these processes.

That said, it's important to keep things in perspective: in the real world it's unlikely you'd have seen the sharpness 'issues' we had with our initial a9 run (that otherwise appeared so drastic in our studio scene). Why? Because (1) you don't typically view images at 100%, (2) there will at least be a plane of maximum sharpness (which in our case, unfortunately wasn't our studio scene on our first run), and (3) your lens and shooting aperture will have far more impact on subject sharpness than which 24 MP sensor was used to shoot it.

To our readers: we offer our sincere apologies, and wish you happy shooting!

A special thanks to forum member Jack Hogan.

Europeana launches 1914 - 1918 thematic collection
Military band, Lorraine 1915, unknown photographer, Max Kranz/Europeana

Europeana, which runs Europeana Photography, the online image archive that includes more than 2 million historical photographs from European collections in 34 countries, is launching the new Europeana 1914-1918 thematic collection, covering World War I.

The collection will be officially launched during the Europeana Transcribathon Campus Berlin 2017 which will be held on 22 and 23 June at the Berlin State Library. At the event teams from three generations and several European countries will compete to digitally transcribe as many World War One documents as possible, and link them to other historical sources such as early 20th century newspapers. Transcribathons are crowdsourcing events and gather people from across Europe and online to create digital versions of handwritten items. Since their launch in November 2016, several million characters and 12,000 documents, from love letters to poems, have been transcribed.

Frank Drauschke, of Europeana 1914-1918 project team says: “Most sources on Europeana 1914-1918 are written by hand, and often hard to decipher. Transcribathon aims to help us ‘polish’ a raw diamond by this making private memorabilia readable online. We utilise the power of our community to transcribe as many private stories and documents from diverse languages and regions of Europe and make them available to the public.”

OnePlus 5 2x tele camera uses 1.6x optical in combination with digital zoom

When we shot our sample images with the brand new OnePlus 5 we noticed that the dual-camera's 2x tele-module did not quite deliver the pixel-level image quality you would expect from the 20MP Sony IMX350 sensor. Images showed low levels of fine detail and looked as if they had been upscaled which would point towards some form of digital zoom implementation.

This has now been confirmed by OnePlus co-founder Carl Pei in a tweet. He clarified that the second lens on the back uses a 1.6x optical zoom and that digital zoom is used to reach the claimed 2x zoom factor. The cropped image is then upscaled to achieve the specified 20MP image size.

The company says it is using its SmartCapture multi-frame technology to make the zoom "lossless" but arguably not everybody would agree with this term. Exif viewers show the focal length of the wide-angle and tele lenses to be 24mm and 36mm equivalent respectively which would mean a 1.5x zoom factor. However, there is a chance Exif isn't taking the SmartCapture portion of the zoom into account.

Some other dual-cam implementations we have seen, for example on the iPhone 7 Plus are using a 2x optical zoom with a smaller sensor than the main camera. It appears OnePlus opted for the same 1/2.8" sensor size in both cameras. An optical 2x lens would probably have required a thicker body or noticeable camera bump.

Hands-on with the Fujinon MK50-135mm T2.9 cine lens

Hands-on: Fujinon MK50-135mm T2.9 cine lens

The Fujinon MK50-135mm T2.9 cinema lens is the second in Fujifilm's new line of MK lenses designed for Super 35 and APS-C cameras. MK lenses are designed to appeal to the emerging production market, offering features and quality typically associated with more expensive cinema lenses at a price point that's attractive to budget-conscious cinematographers. The MK lenses are based on Fujifilm's excellent Cabrio line of cinema lenses (which cost $15K and up), and share the same coatings as well as a similar mechanical build, but at a cost just under $4,000 they're more accessible to a lot of users.

I reviewed the first MK lens, the MK18-55mm T2.9, a few months ago and really liked it. Since the two lenses are designed to work as a set, they're basically indistinguishable except for focal length, so if you want to read my detailed thoughts on how the MK lenses perform I recommend reading my earlier review, which for all practical purposes applies to both lenses.

Hands-on: Fujinon MK50-135mm T2.9 cine lens

If you're not yet familiar with the MK cine lenses, you may be surprised to learn that they use Sony E-mount. Why? Fujifilm wants to address the growing market of independent filmmakers, small production houses, and other professionals who use the Super 35 and APS-C formats. Sony has a huge presence in this market thanks to cameras like the FS7, FS5, and even a-series mirrorless, and many users of these cameras adapt other lenses, such as Canon EF-mount, to their cameras.

What about Fujifilm's own mirrorless cameras? The company has announced plans to release MK lenses in X-mount later this year so that Fujifilm shooters can take advantage of them as well.

Hands-on: Fujinon MK50-135mm T2.9 cine lens

When I tested the MK18-55mm lens earlier this year, I did so with a Sony FS7, a Super 35mm camera mounted on a shoulder rig with rails, a follow focus, and an accessory EVF. However, Fujifilm emphasizes that the MK lenses are also designed for use on similarly sized APS-C sensors, so this time I decided to go that route. Unfortunately, during our short window of time with the lens I didn't have access to a rig for a full setup, so I was limited to basic tripod and handheld use.

When mounted the Sony a6500, it's easy to see how large the MK50-135mm is compared to the diminutive camera. While it's technically possible to shoot this combination handheld, it's not terribly practical thanks to its large size and all mechanical controls.

The great news is that the video I captured looked beautiful, and the lens appears to deliver the same quality that we saw on the MK18-55mm.

Hands-on: Fujinon MK50-135mm T2.9 cine lens

I also tried using the MK50-135mm with the full frame Sony a7R II in Super 35mm mode. The size mismatch is a bit less obvious than with the a6500, however it's no more practical for shooting handheld. That's not necessarily a bad thing – chances are good that if you're considering this type of lens, you're planning to rig it in some way.

In fact, this lens works very well with both the a6500 and a7R II (in Super 35 mode), and would be a great lens to pair with either of them. With a basic set of rails and a follow focus, the setup would work just as effectively as with a dedicated video camera.

Hands-on: Fujinon MK50-135mm T2.9 cine lens

One of the reasons for using cinema lenses is that they often come in matched sets, and this is the case with the MK lenses. The MK18-55mm and MK50-135mm are physically identical, including T2.9 iris, gearing, dimensions, and even weight (right down to the gram). They're also matched optically, meaning they can be interchanged seamlessly without changing the look of the resulting footage.

Why are matched lenses important? In a cine setup the lens is often mounted on rails, and likely has attachments such as a follow focus or matte box. Ideally, you don't want to have to readjust every accessory each time you change lenses, and having physically matched lenses means you can swap them in and out very quickly without needing to readjust everything. The MK lenses are so similar that I would have a difficult time telling them apart without seeing the zoom range printed on the lens barrel.

When it comes to build quality, the MK50-135mm is very solid thanks to its all metal construction. As with most cinema lenses, it's completely mechanical, and every movement feels well damped. It's a pleasure to use and gives one the sense of using a high quality piece of precision equipment.

One thing that sets the MK50-135mm apart from most still photo lenses is the large 200 degree focus rotation angle. This offers a lot more precision than you'll get with the shorter focus throw of a DSLR lens, or the unpredictability of focus-by-wire, so it's easy to make very fine adjustments as your subject moves. The lens includes very precise distance marks, in both English and metric units. This is particularly helpful if you have a separate focus puller who is following the action in a blocked scene.

The MK50-135mm also has a parfocal design, meaning it can maintain precise focus while adjusting the focal length. As still photographers, we don't usually worry about this capability since it's easy to refocus after zooming. In contrast, when shooting video you may actually intend to zoom while recording, and you want to maintain focus on your subject through the entire transition. Losing focus during a zoom can ruin the shot.

I was really impressed with the parfocal performance on the first MK lens, and the MK50-135mm performed to the same standard.

Another common property of cinema lenses is that they resist breathing, a phenomena that causes the lens's field of view to change slightly when focus is adjusted. This becomes particularly important when you're doing something like racking focus between two subjects; you don't want the field of view of the scene to change when you do this as it can be very distracting. The MK50-135mm suppresses lens breathing very effectively, which is not surprising given that the MK18-55mm did so as well.

Based on a couple days of use, I really like the Fujinon MK50-135mm lens, which – not surprisingly – is the same conclusion I came to after testing the MK18-55mm version. They're both beautiful pieces of equipment that are a joy to use, and which deliver excellent results. The fact that there are now two of them spanning the entire 18-135mm range makes me want the set even more. If you're a videographer using an E-mount camera, it's really tough to go wrong with these lenses.

The MK lenses should also appeal to Fujifilm X-mount users. In particular, we found the Fujifilm X-T2 to be a credible 4K video camera, especially since it's capable of outputting F-Log gamma over its HDMI port. We don't yet know the exact release date for the X-mount versions, but Fujifilm tells us it will be later this year, and we saw prototypes at NAB in April.

The MK50-135mm T2.9 will be available in E-mount in mid-July for a price of $3,999, which is just slightly higher than the $3,799 MK18-55mm.
