Joining the α7 and α7R family of full-frame interchangeable lens cameras, Sony's new α7S model puts extraordinary sensitivity, low noise and 4K video quality into the hands of professional
photographers and videographers.
 The 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 -
409600.
The new model is also the 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.
These components allow the camera to process data from all
of the sensor's pixels and output HD and 4K (QFHD 3840 x 2160
pixels) videowhile utilizing the full-width of the
sensor. In addition to the benefits for low-light shooting, the
read out of all pixels frees the video from aliasing, moire and false
color artifacts (as opposed to pixel binning) to achieve high
quality video.
In video mode, the α7S can output 4K videoat QFHD (3840 x 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.
The α7S camera is also 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. Additionally, 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.
Other 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).
The camera also has a Multi-terminal interface shoe that is
compatible with Sony's XLR Adaptor Microphone Kits allowing the use of professional microphone
systems.
The camera is also equipped with the same high-precision Fast
Intelligent AF system as the α7R camera, with improved
low-light AF sensitivity that can go as low as -4EV.
Directly compatible with the 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 offerings from Carl Zeiss and G Series Lenses.
As a whole, Sonys 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. Building on this, Sony has announced
development of a new, full-frame power zoom 28-135mm F4 lens
E-mount lens.
Sony did not provide any pricing and availability of the α7S camera.
