World’s first full-frame sensor capable of full pixel read-out without binning process for movie*1
The sensor reads out image data from every pixel, even during Full HD and 4K*2 movie output, and enables recording and output of Full HD movies at 60p (50p), 60i (50i), 30p (25p) and 24p frame rates, as well as output of 4K movies at a 30p or 24p frame rate, with both resolutions available at both full-frame and APS-C (Super 35mm equivalent) size.

α7S Unparalleled 4K image quality (from Sony: Official Video Release)
BIONZ X image processing engine
Sony proudly introduces the 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.
XAVC S format
The high-bit-rate XAVC S format is provided for serious videographers. Available for the first time in an α camera, it enables Full HD image recording at 50Mbps for extremely high-quality expression and minimal noise. It also employs the Long GOP (Group of Pictures) data compression method to realize efficient movie recording.
Note: Sony recommends using an SDXC memory card higher than Class 10 when shooting movies in the XAVC S format.
Advanced movie functions support a professional workflow
You can fine-tune the look of movies before shooting by adjusting gradation (Black Level, Gamma, Black Gamma, Knee), color adjustment (Color Mode, Color Level, Color Phase, Color Depth) and Detail. Adjusted parameters can be saved along with other settings as a profile, and up to seven profiles can be stored for later recall.
S-Log2 gamma setting
This proprietary Sony gamma setting, featured in professional camcorders, creates a 1,300% wider dynamic range for smooth expression of gradation with reduced whiteout and blackout. Through color grading in post production, you can make the most of the low-noise image and super-rich detail to achieve various types of image expression.
Time code / User bit
As with commercial video equipment, this function provides a "Record Run" setting that only advances the time code while recording, a "Free Run" setting that advances the time code whether recording or not, a drop frame method and a non-drop frame method. The α7S can also output a embedded time code when the clean HDMI output setting is in use.
Note: This function is only available when recording in the AVCHD and XAVC S formats.
120fps (100fps) shooting at HD resolution
120fps (100fps) recording broadens image expression options since a movie shot at this frame rate can be played back at 24p to create stunning 5x slow-motion effects. When 120fps (100fps) recording is selected, movies are automatically recorded at HD resolution (1280 x 720 pixels) in the APS-C (Super 35mm equivalent) crop size.
Clean HDMI output for 4K movies
Non-compressed image output is now possible at 4K (QFHD: 3840 x 2160 pixels) resolution with selectable 30p (25p) and 24p frame rates. You can choose 4K or Full HD output from a menu. The 4K output capability allows recording of high-quality 4K images by a 4K-compatible recorder, as well as 4K output directly to a compatible monitor or TV.
α mount system
Wide-ranging compatible E-mount lenses let you take full advantage of sophisticated features while comfortably shooting movies. For example, specially equipped lenses let you enjoy Optical SteadyShot image stabilization or smooth, steady power zooming throughout the entire zoom range, and all E-mount lenses let you enjoy smooth autofocusing and auto exposure. The camera’s short flange back expands lens options, via mount adaptors, so you can make the most of your current lens collection. The LA-EA4 adaptor, for example, lets you mount professional A-mount lenses and enjoy continuous phase-detection AF.
