From the Manufacturer
Presenting the world’s smallest and lightest1 full frame interchangeable lens camera. With a groundbreaking 35mm large pixel image sensor rated at 15.3-stops of dynamic range and an ISO 409,600 sensitivity2, the α7S reveals astonishing detail and color even in the dead of night. Video excels with Full Pixel Readout, a 4K-optimized sensor and uncompressed 4K output. Fast, intelligent autofocus completes the picture.
35mm large pixel image sensor with 15.3-stops of dynamic range
The groundbreaking α7S features a 12.2 effective megapixel 35mm Exmor CMOS sensor paired with a powerful BIONZ X image processor. The α7S can shoot at a sensitivity range of ISO 100 – 4096004 with low noise and unprecedented 15.3 stops of dynamic range. The extra-large pixels on the α7S collect dramatically more light than traditional cameras to produce beautifully detailed, low-noise images in even the most challenging lighting environments.
12.2MP sensor optimized for 4k and low light video
The α7S is the world’s first 35mm camera to incorporate ‘direct pixel readout’ utilizing the entire width of the full-frame image sensor without line skipping or pixel binning. Therefore in both HD and 4K video acquisition it can read and process data from every one of the sensor’s pixels. This allows video shooters to utilize all of the artistic and creative benefits provided by the unique sensor.
High ISO up to 409,600 w/ fast AF in light as low as EV -4
Equipped with the same high-precision Fast Intelligent AF system as the award-winning α7R camera, the α7S drastically improves AF sensitivity in low-light that can go as low as EV -4.
New-generation RGB filter with gapless on-chip lens design
The larger than normal pixel size on the 35mm full-frame image sensor with effective 12.2MP, employs Sony’s latest image sensor technologies on the α7S. To boost the image sensor’s light collection efficiency, a new-generation RGB color filter has been adopted, in addition to the gapless on-chip lens design, light concentration technology and photodiode expansion technology delivers unprecedented high sensitivity and low-noise levels with high dynamic range in every light condition from severe low light to bright sunlight. By applying an AR coating on the surface of the seal glass over the image sensor, ghosting and flare have been minimized, further contributing to the α7S’s high image quality.
Uncompressed 4:2:2 Full HD and 4K QFHD output via HDMI1
In video mode, the α7S can output 4K video at QFHD (3840x2160) in 4:2:2 to an optional external 3rd party 4K recorder via the HDMI1.
50Mbps XAVC S 1920x1080 at 60P, 1280x720 at 120P
For the first time ever in a Sony α camera, the α7S adopts the workflow-friendly XAVC S recording format in addition to AVCHD and MP4 codecs. XAVC S format allows for full HD recording at a data rate of 50 mbps with lower compression for improved video quality. The α7S can record full HD (1920x1080) at frame rates of 60p, 60i, 30p and 24p directly to a compatible memory card. Video modes can be changed from full-frame to APS-C (super 35mm equivalent) if desired, and in this crop mode, the camera can support high frame rate 120fps shooting at standard HD resolution (1280 x 720p), creating a 5x slow-motion effect.
Silent shutter mode for discreet shooting
Silent shutter mode is ideal when discretionary shooting is required; like capturing a recital or wildlife. Activating the silent shutter eliminates the use of the mechanical shutter and therefore shutter noise by utilizing an electronic shutter in its place.
3.0" 1.23M dot LCD tilts for high and low angle framing
The tiltable 3.0” (1,229k dots) Xtra Fine LCD Display makes it easy to photograph over crowds or low to capture pets eye to eye by swinging up approximately 84 degrees and down approximately 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, α7S 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.
Pro-workflow w/ Picture Profile, S-Log2 and time code
The α7S is equipped with S-Log2 gamma. Common to Sony’s range of professional video cameras, S-Log2 expands the dynamic range by up to 1300% to minimize clipped highlights and loss of detail in shadows. The α7S includes a picture profile that can adjust settings like gamma, black, level and color adjustment, and can be saved for use in a multi-camera shoot. It also has Full HD and 4K base band HDMI output, time code/user bit for easier editing, synchronous recording feature with compatible devices, various marker and zebra displays on both the LCD screen and viewfinder.
Audio level controls, AAC/Linear PCM2, optional XLR kit
The α7S has a Multi-terminal interface shoe that is compatible with Sony’s XLR Adaptor Microphone Kits (XLR-K1M plus a new model under development), allowing the use of professional microphone systems.
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 computer.11
High contrast 2.4-million dot XGA OLED Tru-Finder EVF
View every scene in rich detail with the XGA OLED Tru-Finsder, which features OLED improvements and the same 3-lens optical system used in the flagship Sony α99 Full Frame 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.
Compatible w/ Sony E-mount lenses and many others3
Directly compatible with the growing family of E-mount Full Frame lenses, the α7S camera can also be used with A-mount and others lens systems with optional adapters. Sony’s complete α lens system includes several premium offerings from Carl Zeiss and G Series Lenses. Sony’s E-mount lens system is particularly well-suited for video shooting, with a variety of models containing “movie-friendly” features like smooth focusing, powered zoom control, and silent iris/aperture control.

Top customer reviews
I have used every camera made over the past 7 years. ALL of them, even DSLRs. I only review and write about the ones that move me, the ones I like, the ones that offer something special whether that is in the form of usability, IQ, abilities, lenses, versatility, etc.
The A7s offers so much, that it is probably the favorite camera I have ever reviewed or used in 7 years. I have loved and adored many cameras for what they offer. The Olympus E-M1 is a micro 4/3 masterpiece. The lenses for that system are the best there is. The Sony RX1 and RX1r..magical and quite special once you know how to use it and exploit what it offers. The Leica M 240, again, it can provide an emotional experience while delivering class leading IQ.
But today I am talking about the virtues and benefits of the Sony A7s. I find it sad that many just look at the words "12MP" and assume it is not good for photos. NONSENSE 100%, and that is a fact.
In reality, 12MP is more than 99.8% of us will ever need (see my review at my site for more on this) ad I can make beautiful 20X30 prints from an A7s file (just got one back today) just as I used to do with my 4MP Nikon D2hs. Huge MP is NOT needed for large prints! Now if you want to shoot massively detailed landscapes, go for medium format as that will deliver what you need more than any 35mm based camera. For everything else, the A7s is plenty.
Now there are those who are "pixel peepers", who only get enjoyment from viewing their images 100% on a computer screen (which is not a way to view a photo and has nothing to do with real photography). If this is you then you will need a 36MP monster to satisfy your needs.
The A7s has LOADS going for it over an A7 or A7r, below are a few of those things:
1. Low light abilities - I am NOT talking high ISO here, I am talking Auto Focus ability. This camera has an uncanny ability to focus in pitch blackness, even without the AF assist light. You will never be in a situation where the A7s cannot focus.
2. High ISO - As of July 2014, there is NOTHING that can touch this fro high ISO use. I have decided that I can now go up to ISO 102,000 and have a usable image. Color stays, DR stays. Amazing. ISO 6400 is like many cameras at ISO 400. This opens up all kinds of creative possibilities and things no one has ever been able to do before. It is significant just for that reason alone.
3. AF Speed. This is faster to Af than the A7 and A7s, no question.
4. Quiet - This camera is much quieter than the A7 and A7r and can even be shot in SILENCE. As in ZERO noise. I shot a scene at ISO 80k in a dark room. No one knew I took the shot and it was quiet in a room that echoed severely. No one would have believed me if I told them I took a shot as it was seemingly impossible to do without a flash.
5. Video - Amazing video capabilities even at ISO 102,000.
6. Leica M Glass friendly - The A7 and A7r and even the Leica M itself has issues with some wide angle M mount lenses (the M 240 has issues with 3rd party wides) that create colored edges and unusable color images. The A7s is the 1st full frame digital that can use a lens like the 15 Voigtlander without any real issues, IN COLOR! This is huge for those with Leica M glass. Huge. I use the 15, 35 1.2 and others and they look beautiful, in some cases beating what comes from the M240 in good light. Low light? The Leica can not compete with the A7s.
7. AWB and color - The AWB and color is improved with the A7s over the A7 and A7r, this is a fact.
So there are just 7 of the reasons the A7s is way more useful than the A7 or A7r for my tastes. Resolution, again, 12MP is plenty for any web use and any print size 99.9% of us will print. If you are a person who is into photography and NOT pixel peeping you will adore this camera without question. It opens up all kinds of possibilities that were never there before. Slap on a 50 0.95 from Mitakon or even Leica and your world will be rocked.
The camera is solid, has a great EVF and LCD and the ONLY complaint I have is that it does not have in body IS. If it had the Olympus 5 Axis IS it would be my dream camera. Really.
New lenses are on the way and even Zeiss has some amazing new offerings coming in MF lenses that will work with the Sony. For me, this 12MP beauty is all I really need but I still am emotionally attached to my Leica M and Olympus E-M1 ;)
To those who gave this camera low ratings or say it is no good for photos, you are wrong. It's superb for photo or video and beats out most cameras i have used in recent years. You can see tons of photos in my review if you just google for it.
Sure there will always be new cameras..an A7x or A7T..but for now, July 2014, this one is at the top of the Sony Heap for me.
The A7s for me gets 5 stars.
When I read the announcement for the upcoming Sony A7s I was both nervous and excited. 12mp would be a major drop from 36mp, but all the other improvements had me drooling. Clean, usable ISO past 10,000, 120fps 720p video, 15 steps of dynamic range, all in a body half the size of my d800. When earlier reviewers started comparing the camera's picture quality to medium format images (in color quality and accuracy not resolution) it almost sounded all too good to be true. Especially for Sony! Maybe I wouldn't have been so skeptical if all this was coming from Canon or Nikon, but Sony? I remember shooting with there first few generations of DSLRs and being very disappointed. Now they are claiming there little A7s can do it all and more? Well yesterday mine arrived. All the hype was true.
For yesterday's wedding I brought a Canon 5D MKIII and this little guy, hoping to shoot with it here and there if I could figure out the menus quickly enough. This was my first mirrorless camera and it definitely handles different from a DSLR but in a very nice way. The menus and layout was all simple enough that I was able to do a lot of shooting with it yesterday. I shot video and am so happy with the results. The image came out so clean. The 50mb codec allows for so much latitude. For 120fps shooting I doubled the shutter to 1/250. Worked great during the day -- worked just as good when the sun went down and I jumped past 10,000 ISO to maintain exposure.
Today I've delved into the menus a bit deeper and am pleasantly surprised by the amount of customization. Almost every button can be remapped to the user's preference. If you have a set of features you regularly access, no more diving through menus, just map 1 of 3 custom buttons to do it. Or remap one of the other existing buttons. I've also been shooting RAW images and again, have been very impressed. Great dynamic range -- great color accuracy -- no noise. I guess I forgot what 12 megapixels looks like. It's more than enough for your average print. For enlargements I'm better photoshop's newer upscaling algorithms will handle things just fine.
Both the OLED EVF and LCD are beautiful and incredibly accurate. The camera has a little sensor in the EVF that knows when you are looking through -- that way it knows when to switch from LCD to EVF. It's nice that they let the user even turn that sensor off if you want to manually switch the display.
After 2 days of very heavy use, I'm pretty sold. I'll post updates as I continue to use the camera, but at this rate I'll probably buy another one in a month or two.
Low light is unbelievable I can record things with this camera that I can barely see with my eyes
Still image quality is superb the best pictures I've ever taken are with this camera I have to many 24x36 prints on my wall from this camera
Zebra striping and focus peaking make taking perfect pictures and video to easy
There are only two caveats the life of the batteries as others have mentioned really is pretty lackluster you can get by with them but I'm going to have to do something about it
And its getting better but lens selection is still pretty weak
The two problems dont bother much at all once I look at the quality of images taken with this camera
Thank you Sony for not playing the stupid megapixel war game
