It's all the full-frame performance you ever wanted in a compact size that will change your perspective entirely. NFC: One-touch remote, One-touch sharing
From the Manufacturer
Sony® α7R Full Frame Compact Interchangeable Lens
Digital Camera
No other full frame, interchangeable-lens camera is this light or this portable. Features 36MP of rich detail, a true-to-life 2.4 million dot OLED viewfinder, Wi-Fi® sharing and an expandable shoe system. It's all the full-frame performance you ever wanted in a compact size that will change your perspective entirely.
Technology
World's smallest and lightest1 interchangeable lens full-frame camera
Sony's Exmor® image sensor takes full advantage of the Full-frame format, but in a camera body less than half the size and weight of traditional full-frame DSLRs.
Ultimate full frame 36.3 MP resolution with no optical low-pass filter
The newly developed 36.3-megapixel 35mm full-frame Exmor® CMOS sensor delivers unbelievably high resolution in combination with high sensitivity and extremely low noise. Sony removed the optical low-pass filter to bring out the full potential of the sensor and lens, thus achieving an enhanced sense of clarity with supremely realistic details to the very edges of your photos. An AR coating also reduces flare and ghosting.
Gapless, optimally positioned on-chip lenses
Sony optimized the design and positioning of every on-chip lens (OCL) covering every pixel to significantly enhance light-gathering efficiency. A gapless on-chip lens design eliminates the gaps between the micro-lenses to collect more light. Moreover, each on-chip lens is optimally positioned depending on its location to accommodate the sharper angle of light entering the periphery, which is caused by larger sensor dimensions being teamed with the E-mount's short flange-back distance.
New BIONZ® X image processing engine
Sony proudly introduces the new BIONZ® X image processing engine, which faithfully reproduces textures and details in real time, as seen by the naked eye, via extra high-speed processing capabilities. Together with front-end LSI (large scale integration) that accelerates processing in the earliest stages, it enables more natural details, more realistic images, richer tonal gradations and lower noise whether you shoot still images or movies.
Fast Intelligent AF for responsive,
accurate, and greater operability with
full frame sensor
The high-speed image processing engine and improved algorithms combine with optimized image sensor read-out speed to achieve ultra high-speed AF despite the use of a full-frame sensor.
Fully compatible with Sony's E-mount lens system and new full-frame lenses
To take advantage of the lightweight on-the-go body, the α7R full frame compact interchangeable lens digital camera is fully compatible with Sony's E-mount lens system and expanded line of E-mount compact and lightweight full-frame lenses from Carl Zeiss and Sony's premier G-series.
Additional Features
Direct access interface for fast, intuitive shooting control
Quick Navi Pro displays all major shooting options on the LCD screen so you can rapidly confirm settings and make adjustments as desired without searching through dedicated menus. When fleeting shooting opportunities arise, you'll be able to respond swiftly with just the right settings.
High contrast 2.4M dot OLED EVF for eye-level framing
View every scene in rich detail with the XGA OLED Tru-Finder, which features OLED improvements and the same 3-lens optical system used in Sony's flagship a99 DSLR. The viewfinder faithfully displays what will appear in your recording, including the effects of your camera settings, so you can accurately monitor the results. You'll enjoy rich tonal gradations and 3 times the contrast of the α99. High-end features like 100% frame coverage and a wide viewing angle are also provided.
3.0" 921k dot LCD tilts for high and low angle framing
The tiltable 3.0" (921k dots) Xtra Fine™ LCD Display makes it easy to photograph over crowds or low to capture pets eye to eye by swinging up approx. 84° and down approx. 45°. Easily scroll through menus and preview life thanks to WhiteMagic™ technology that dramatically increases visibility in bright daylight. The large display delivers brilliant-quality still images and movies while enabling easy focusing operation.
Simple connectivity to smartphones via
Wi-Fi® or NFC
Connectivity with smartphones for One-touch sharing/One-touch remote has been simplified with Wi-Fi®/NFC control. In addition to Wi-Fi support for connecting to smartphones, α7R also supports NFC (near field communication) providing "one touch connection" convenience when transferring images to Android™ smartphones and tablets. Users need only touch devices to connect; no complex set-up is required. Moreover, when using Smart Remote Control — a feature that allows shutter release to be controlled by a smartphone — connection to the smartphone can be established by simply touching compatible devices.
PC control w/ remote video capture control
Remote Camera Control allows you to control your α7R from your PC using a USB cable. Feature control has also been updated to include video capture control.
14-bit RAW output for rich tonal gradation
14-bit RAW image data of extremely high quality is outputted by the α7R. This data fully preserves the rich detail generated by the image sensor during the 14-bit A/D conversion process. When developed with Sony's Image Data Converter RAW development software, these images deliver the superb photographic expression and rich gradation that only 14-bit data can offer.
Full HD movie2 at 24p/60i/60p w/uncompressed HDMI® output
Capture Full 1920 x 1080 HD uncompressed clean-screen video files to external recording devices via an HDMI® connection in 60p and 60i frame-rates. Selectable in-camera AVCHD™ codec frames rates include super-smooth 60p, standard 60i or cinematic 24p. MP4 codec is also available for smaller files for easier upload to the web.
Multi-interface Shoe for flash and microphone flexibility
Unlike conventional cameras, the α7R features the advanced Multi-Interface Shoe that dramatically expands compatibility with Sony digital imaging accessories, thus raising the potential for photo/movie shooting.
4K Still image output by HDMI®8 or Wi-Fi® for viewing on 4K TVs
Enjoy Ultra High Definition slide shows directly from the camera to a compatible 4K television. The α7R converts images for optimized 4K image size playback (8MP). Enjoy expressive rich colors and amazing detail like never before. Images can be viewed via an optional HDMI connection8 or via WiFi®.
TRILUMINOUS™ color outputs wider color gamut to compatible devices
TRILUMINOS™ Color technology, allows you to experience photos and movies in rich, natural colors on any TV equipped with a TRILUMINOS Display™. The expanded color gamut immerses you in those unforgettably colorful moments, from the complex shades in a shimmering blue sky to the delicate skin in a baby's face.
PlayMemories™ Camera Apps allows feature upgrades
Personalize your camera by adding new features of your choice with PlayMemories™ Camera Apps. Find apps to fit your shooting style from portraits, detailed close-ups, sports, time lapse, motion shot and much more. Use apps that shoot, share and save photos using Wi-Fi® that make it easy to control and view your camera from smartphone, and post photos directly to Facebook or backup images to the cloud without connecting to a computer11.
Image Data Converter
Advanced features enable manipulation, conversion and management of full-resolution RAW images. You can expertly adjust exposure, white balance, tonal curves, saturation, contrast, hue and sharpness — as well as apply DRO and vignetting compensation. Bundled Remote Camera Control software also lets you remotely activate and deactivate still/movie recording and control various camera settings from a PC.
Vertical Grip Capable
Enjoy long hours of comfortable operation in the vertical orientation with this sure vertical grip, which can hold two batteries for longer shooting and features dust and moisture protection.
Mount Adaptors
Both the LA-EA4 and LA-EA3 are full frame compatible adaptors that let you the α7R with any A-mount lens. Additionally, the LA-EA4 features a built-in AF motor, aperture-drive mechanism and Translucent Mirror Technology to enable continuous phase-detection AF. Both adaptors also feature a tripod hole that allows mounting of a tripod to support large A-mount lenses.

I am SO pleased with this little body I don't even know where to start. The resolution and low light capability are nothing short of amazing. Paired with a Zeiss 55 FE1.8, there is NOTHING out there - at any price - that will challenge the resolution and separation this little set up will produce; in a wide range of conditions, even at twice the bulk and weight. I have dozens of exceptional lenses and around 10 bodies left, and by FAR - the A7r with the Zeiss are my bread and butter - day in, day out.
It is not a forgiving rig - make no mistake - it will amplify any and all errors on your part, so be prepared to revisit your basic skill practice. It is SO sharp that any technique weakness you have WILL be apparent. I spent the first day setting the customizable button settings and haven't touched the mode dial since - it's on M and will stay there for ANOTHER 100k exposures. The EVF is phenomenal and compared with just the last generation, is largely lag free.
I primarily do portraits and environmental editorial work and for my niche, it absolutely ROCKS. The EF focus is a portrait artist's dream feature and it works under most conditions once you learn how to use it. There is a learning curve for this body, but the results are so spectacular it's a non-issue. Landscapes are right at the peak of this little guy's power curve and in capable hands, you will HAVE to go to medium format to overtake it. Resolution and sharpness (with the right glass of course) is stunning, colors are absolutely perfect and I have found no weakness in any use where a tripod is a viable option - NONE.
The stories of a loud shutter are grossly overstated. The myths of shutter shake are complete BS. Any image that comes out with anything less than breathtaking sharpness and resolution is due to operator error - period.
Sports? Not my first choice. Fast action? Probably not. Uber long lenses and wildlife? Maybe but the tiny body hanging off a 400mm f2.8 is disconcerting, visually as well as tactically. Huge glass needs a hefty body for balance and the A7r just doesn't have it, and while the shutter isn't a lot louder than any other FF dslr, the lack of a first curtain or silent mode makes other options better for skitterish critters.
Pros for me:
Size and weight are ideal. Solid but not heavy or bulky.
INFINITE glass possibilities. All my old Minoltas, Voightlanders, Leicas, Zeiss, and (now) repurposed Canon and Nikon FF glass produce BETTER results on the A7r than they ever did on their native bodies.
A (finally) standard hot shoe means lighting possibilities are VASTLY improved over previous Sony offerings. Strobes, speed lights and bare bulb - old or new - they're all usable again - YAY
EVF is astonishing. WYSIWYG and it really is WYG
Focus peaking makes focus stacking SO easy, even a caveman like me can do it.
Tethered use - via lightroom or Capture one - sorely absent in previous Sony models.
Wireless triggers (ramp, bulb, interval and time lapse in addition to a zillion different triggering methods like light, vibration, sound, facial recognition, etc) open up some amazing possibilities.
While not silent, it is small and unobtrusive for street use - not at all intimidating and it can actually be carried all day without a chiropractor on call. (And there are some truly phenomenal 20-40mm pancakes out there that SHINE on this body)
Good 3rd party batteries are cheap and perform well, and they're small - easily fit 3+ in a pocket.
Assign almost any button to the functions YOU use most - and there are PLENTY of buttons.
Highly customizable as far as your presets and ranges - if you know what you normally use and have some time under your belt, you rarely need to go into the menus.
Eye Focus - a life saver for super fast glass in a portrait setting - and YES - it really works ;)
If I do my part, this little body delivers STUNNING images consistently.
With the dedicated lenses, no switching to fine tune (with auto zoom!) focus manually - and with peaking, precise control is easy
Cons for me
Limited multiple exposure capability (but I'm hoping for a firmware update to address it beyond the 2 exposure current limit)
CD focus only unless using the Sony adapter with PD (which works well most of the time but it's noisy as hell and feels like something might break)
Useless for IR - the filter is ridiculously effective - I'll have one converted when I can swing a second A7r body)
Battery life. Around 300 images with EVF and LCD in use and radio trigger on top (but I carry several batteries at all times, so not a game breaker - and swap out is a 10 second deal).
Movie button is poorly placed (I have it shut off so it only works if mode dial is set to movie though - so again not a big problem)
On a speed plate, the LCD is hard to swing out ... and speaking of LCD - I miss the fully articulated screen on the A77 at times like overhead or ground level shots and especially for verticals
In a nutshell, for my work, it isn't perfect but it's pretty darn close. It's paid for itself many times over just in the last several months, and has never missed a beat. If and when it dies, I'll gladly buy another.
This is NOT a camera for beginners in any sense. Less than flawless technique is mercilessly punished and glaringly obvious. That having been said, with the right glass, when you get it right, the results are TRULY breathtaking. After ~30 years, 4 of my best 10 images have been made with this body in the last year and I have no reason to believe it's going to let up any time soon.
10/10 if it fits your shooting style and intended use.
I am still getting used to the a7R and where all the buttons are located. Right off the bat, you have to love the size and lightweight of the body. I think that the a7R and 2 lenses and flash would weigh the same as the Canon 5D and 1 lens. I have also owned Leica equipment and the a7R reminded me of how easy it is to just have the camera around since it is smaller and lighter. The programmable buttons are great and I think after set up the camera can do everything I would like. I feel confident that when I take a picture it will turn out well.
I also like the options for wireless controlling the camera from the iPhone app or small wireless remote control. I have also gotten a small Sony flash.
OK, downsides. The major complaint is the shutter which is a little loud and has a lot of moving parts. Normally with the 35mm, I just snapped away. However, I can think of many situations where you might wish it was quieter. Second, not a real complaint but my adapting to the Sony is the electronic viewfinder and how quickly it goes to sleep to save power. You have to push down on the shutter button to get it to wake up. Which leads me to No. 3 - power consumption. The camera does consume its battery relatively quickly. I have gotten the grip accessory which lets you insert two batteries. A good thing to get and it actually makes the camera easier to hold.
With the 35mm F2.8, the Sony focuses quickly and the pictures are very sharp - excellent - from F4.0 onwards. The 35mm really shows off the high resolution of the Sony 36.4 MP and you can pixel peek all day long. You can read some of the reviews of the 35mm and you know that this lens is one of the best available at any price. This is a great lens to leave on the camera all the time. It is very compact and the combination A7R and 35mm is a great combination for traveling or walking about. It gives you the portability of a small snapshot camera but the resolution of the most professional large body device. I just got the Sony 24-70mm F4.0 so I cannot comment.
On adapting Canon mount lenses, I have tried the A7R with the Canon 24-70 F2.8 L II - the new one - with the Metabones adapter. My major issue is that the focusing took a long time with some hunting. I guess I should be amazed that it worked at all! The auto exposure worked fine and the Canon lens really showed its great resolution at all focal lengths. I don't think this is the combination for street shooting but it would work for some carefully composed pictures. The Canon 24-70 on the Canon 5D III is works beautifully so I think the fault is the hybrid mixing of two systems. I also used the A7R with several Zeiss Canon mount lenses I have - the 21mm and the 18mm - and they worked fine and are very sharp. In this case, the focusing is manual.
My conclusion is that native Sony/Zeiss lenses work great and focus quickly. Canon mount lenses do not focus as quickly but it is a cheap price to pay to be able to use your Canon lenses on the Sony system when you want.
The bottom line for me is that I really enjoy the a7R. It is small and compact and is the kind of camera that you will carry on that next trip to Asia or Europe - or to see the kids play. The light weight and size make it easy to throw in a briefcase or camera bag. Finally, with the Metabones adapter, you can use your other lenses and see if they are up to 36 MP. I am happy I bought the a7R and I am still finding out its many features. Fun!
Edit:
I bought the Mark 2 but wanted to try this again as a backup since it is so light weight and the sensor is terrific. I planned to use it only on wider angle lens such as the 35 mm f2.8 ZA. However, it was so hard to get good sharp images at 1/30 while I could hold it to 1/8 with the Mark II. The mechanical shutter just jerks around when I push the shutter. I think with good practice, it might be able to be tamed somewhat but I gave up eventually. Such as nice camera but with major flaws.
