Description

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 Ξ±7S 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. Technology 35mm large pixel image sensor with 15.3-stops of dynamic rangeThe groundbreaking Ξ±7S features a 12.2 effective megapixel 35mm Exmor CMOS sensor paired with a powerful BIONZ X image processor. The Ξ±7S 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 Ξ±7S 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 videoThe Ξ±7S is the world’s first 35mm camera to incorporate β€˜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 -4Equipped with the same high-precision Fast Intelligent AF system as the award-winning Ξ±7R camera, the Ξ±7S drastically improves AF sensitivity in low-light that can go as low as EV -4. New-generation RGB filter with gapless on-chip lens designThe 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 Ξ±7S. 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 Ξ±7S’s high image quality.Uncompressed 4:2:2 Full HD and 4K QFHD output via HDMI1In video mode, the Ξ±7S 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 120PFor the first time ever in a Sony Ξ± camera, the Ξ±7S 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 Ξ±7S 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. Additional Features Silent shutter mode for discreet shootingSilent 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 framingThe 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 NFCConnectivity 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, Ξ±7S also supports NFC (near field communication) providing β€œone 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 β€” a feature that allows shutter release to be controlled by a smartphone β€” connection to the smartphone can be established by simply touching compatible devices.Pro-workflow w/ Picture Profile, S-Log2 and time codeThe Ξ±7S 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 Ξ±7S 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 kitThe Ξ±7S 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 upgradesPersonalize 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.11High contrast 2.4-million dot XGA OLED Tru- Finder EVFView 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 Ξ±99 Full Frame DSLR.

  • Nice light cam
Color: Black Set: Base
I bought the Sony A7S because I wanted a lighter rig for event photography. I was getting tired of lifting a 4.5 lb pro DSLR rig (including flash) to events where I'd be standing, holding the camera for 3+ hours. The A7S (with Godox flash and 24-70 F/4 lens) is half the weight of my previous DSLR rig. So mission accomplished there. In terms of usability, it took me an hour or so to get used to the menus and set the camera up the way I like it. People complain about the menus but I really didn't find it any better or worse than any other professional DSLR. If I couldn't find something I googled it and quickly got an answer to direct me to the right menu option. In terms of build quality, both the A7S and the 24-70 f/4 lens are a class act. It's very apparent this camera is a step above other semi pro cameras. The finish is almost museum quality. In term of usage, the A7S is a mixed bag. The photo quality is excellent, but it strains to compete with a pro 20 megapixel plus full frame DSLR. The lower megapixel count leaves the image quality in average light about half way between a great aps-c camera and a full frame. The low light capabilities of the A7S are really quite good. I usually shoot events in dark settings using 1/60th of a second, ISO 1000 at f/4. Most of my shots are at around 24mm. I noticed less noise in the dark areas than a comparable DSLR. My first impression is that the A7S has about a 2 stop noise advantage over the typical DSLR. My old rig, I would comfortably shoot up to ISO 1600 and feel okay handing clients photos. With the A7S I could go as high as ISO 6400 no problem (and perhaps even higher). I was hesitant to give the D7S five stars because the autofocus is not comparable to a semi pro DSLR. It seems that the autofocus takes a little bit of time to confirm focus. Perhaps this is the lens I'm using. By no means is the autofocus slow, but my previous semi pro DSLR rig, I could mash on the shutter button and be pretty sure to get focus no matter what. I was still able to work okay with it, but there might be a few cases where I might not get the shot because I'm taking that shot in a real hurry. What really amazed me is that I don't have to touch the photos in post. With my old DSLR, I was always adjusting exposure, adjusting light room sliders, white balance, etc. With this cam, no post adjustment is needed at all. Very, very occassionally I might adjust the exposure, but this is primarily due to the decisions of the flash unit. From that perspective, this cam really speeds up my work, specially when I'm trying to get a lot of photos processed for a client in a very short period of time. Video from this camera is awesome, especially in low light. I've shot this cam in low light that I would not even attempt with any other camera/video camera and the result is little noise (when there is practically no light to work with) and no noise with a slight amount of light to work with (we're talking candle light). The resulting video in low light looks exactly as I remember seeing the scene with my own eyes, and that was using auto setting!. Some people complain about battery life but I was able to get about 200 shots before the battery showed 1/4 full. I swapped out the battery and 2 rechargeables in my godox flash and carried on for a while. I could see some gigs where I might go 4 batteries. I have a battery grip that holds two batteries (cheap after-market $35 unit) so I can always go to that if I want to do an 800+ shot day. The main objectives for me have been met. The rig is small and less than half the weight of my previous DSLR. I gave up on some resolution compared to my 20+ megapixel rig. I gained two stops of low light. The images are rock solid so I don't even have to adjust them in post, that saves me time (and the smaller image size is faster for downloading, etc.). Autofocus isn't such that I could get shots mashing on the shutter in all situations, but workable for event photography. All in all, if you are willing to accept the trade offs between this cam and a large pro DSLR rig, it's a great choice. The cam is really the "king" of low light, for both stills and video, which is quite commendable and in a small package to boot. ... show more

  • The Low-light / Street / Video Beast
Color: Black Set: Base
I had little interest in this camera when it was first announced, but after reading some of the reviews I decided to give it a chance. I was hesitant for the obvious reason: 12 MP. What is this, 2008? I understand why having fewer, larger pixels results in better high-ISO performance, but the previously reigning low-light king (according to DxOMark), the Nikon Df, has 16 MP, so 12 seemed a little stingy. As a street photographer who often shoots from the hip, literally, I like to have the option to crop, and 12 MP would leave me precious little margin for error. 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. ... show more

  • Great camera, works perfect in low light, takes time to master all of the functions.
Color: Black Set: Base
The sony A7S camera is absolutely amazing. It shoots wonderfully in low light. I bought this product used and it came with everything you would have expected. It was even wrapped up nicely in a foam sleeve. The sensor was spotless and no signs of wear and tear. The strap was never opened. As soon as I started working with the camera I fell in love with it. It practically sees in the dark. Buyer beware tho, the camera does everything and packing everything into a small interface means there are allot of settings that do not seem apparent out of the box. Sony has an app store that allows developers the ability to build in extra functions, but it ships missing a few key features. You must download an app to perform time lapse photography. Once in this app you have to exit the app to return to normal shooting. Not a deal breaker, but kind of annoying especially since I'm an amateur photographer and when I'm shooting, I want to be taking shots not setting up the camera. As far as customization, the A7S does allow you to set up 3 buttons to match your shooting style, putting features you use most at your fingertips. All in all, grab a few lenses and this camera will take care of the rest.
