World Class Size and Dynamic RangePresenting the α7S, the world's smallest1 full frame interchangeable lens camera. Images and video come alive with a breakthrough dynamic range. ISO sensitivity up to 409,600 reveals astonishing detail and color even in the dead of night. Video excels with Full Pixel Readout without pixel binning, a 4K–optimized sensor and uncompressed 4K output via HDMI.
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.

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.
First, the bad: Yes, 12 MP is limiting. People who tell you otherwise are either being disingenuous or only do photography where there's plenty of time to compose and adjust zoom or get closer as necessary. Any photography that demands capturing fleeting moments, including street and wedding, is going to suffer from the cropping constraints.
And yet, I still consider this the full-frame street photography king for two reasons: High ISO performance and the silent shutter option. I'm not interested in making night look like day, but the high-ISO performance allows me to use faster shutter speeds and greater depth of field so my subjects are neither blurry nor out of focus. I've never used any images above 6400 from the other cameras I've recently owned (D800, A7, E-M5), but with this camera I feel comfortable using 12800 and even 25600. People who say images are "usable" up to 51,200 probably have a different definition of usable than I do. Some claim the noise on this camera has a film grain quality to it; I think all digital noise is ugly, and if I want grain I can add it in post. Good thing there's just less noise with this sensor.
You may have seen the High-ISO shootout on the famous review website that begins with DP. Of course I could always use the 36 MP images from my D800 and shrink and normalize to 12 MP and get noise that's only a little worse than the A7S, but the D800 isn't very discreet on the street. I could get an A7R and try the same thing, but again, the shutter noise...
And discretion is another area where the A7S shines, both in its size and its electronic silent shutter option. I love the silent shutter on my RX100 and the very quiet E-M5 and Ricoh GR shutters. The A7S silent shutter is completely silent, as advertised. This opens up new worlds of possibility for close-quarter street photography, and was decisive in my decision to keep this camera. Just note that you will get rolling shutter effects if the camera is moving fast or with things like lightning. In such cases you can switch back to the regular or electronic first curtain shutter.
Autofocus performance is as good or better than that of my A7, especially in low light. This is puzzling because the A7 has hybrid phase detection whereas the A7S only uses contrast detection. I assume the smaller number of pixels and better processing/implementation are responsible for that discrepancy.
It's too early to say how 4K video will stack up against the GH4 since the Atomos Shogun isn't available yet. If I were a dedicated videographer just starting out I would probably buy the GH4, but for somebody who is already invested in FE-mount lenses this A7S is the obvious way to go. If you only need 1080p this camera is overkill--the A6000 and other cameras shoot very nice 1080p for a fraction of the price.
THE BOTTOM LINE:
Speaking of price, this camera is not cheap. At current street prices it's a full thousand dollars more than the A7 body, and the A7 is already a very good camera that has double the pixel count. So, should you buy it? I would say yes only if you need at least TWO of the three things at which it excels. Low-light video? ABSOLUTELY. Low-light street photography? YES. But if you only need excellence in ONE area, or do a different kind of photography, there are cheaper and/or better options. This will replace the A7 as my street photography staple, but I'll hold on to my D800 for high-res applications until the next iteration of the A7R addresses some of that camera's lingering issues, at which point I may go all in with Sony's full-frame mirrorless system. Maintaining two systems is expensive and inefficient, and I really think Canikon are losing the future by not recognizing that mirrorless is it.
