Sony α7S Full-Frame Camera puts 4K video quality into the hands of professional photographers and videographers

Joining the acclaimed α7 and α7R family of the world’s smallest full-frame interchangeable lens cameras, Sony’s new α7S model puts extraordinary sensitivity, low noise and spectacular 4K video quality into the hands of professional photographers and videographers. Sony α7S is equipped with the same high-precision Fast Intelligent AF system as the α7R camera, with drastically improved low-light AF sensitivity that can go as low as -4EV.

Bionz XThe innovative α7S camera features a newly developed, 12.2 effective megapixel 35mm Exmor CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 4096002 with unprecedented dynamic range and low noise. 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.
Sony_a7S_combinationSony’s new α7S model is world’s first camera to utilize the entire width of a full-frame image sensor in 4K video acquisition, and does this without cropping or line skipping as it can read and process data from every one of the sensor’s pixels. This allows 4K video shooters to utilize all of the artistic and creative benefits provided by the unique sensor. With the new α7S camera, the high-speed read out of the 35mm full-frame image sensor combined with the high-speed processing of the BIONZ X processor enables significant improvements in video quality.

Sony α7S features a newly developed on-sensor technology that allows it to optimize the dynamic range throughout the entirety of the ISO50 – 409,600 sensitivity range. This on-sensor technology also broadens the range of tonal gradation in bright environments and minimizes noise in dark scenes, allowing the camera to deliver impressive results in these extreme conditions where other cameras (and image sensors) typically struggle.
Sony_4KIn video mode, the α7S can output 4K video4 at QFHD (3840×2160) to an optional external 3rd party 4K recorder, and can record full HD (1920×1080) 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.
Sony_α7S_card_slotOther specialist video functions on the new camera include 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 and can dual record XAVC S as well as MP4 (1280×720 @30p).
Sony_E_MountDirectly compatible with the growing family of E-mount lenses, the α7S camera can also be used with A-mount and others lens systems with optional adapters. Sony’s complete α lens system now includes 54 total lenses for both A and E mounts, including several premium offerings from Carl Zeiss and G Series Lenses. Pricing and availability of the α7S full-frame interchangeable lens camera will be announced at a future date.
