Sony has just announced the new A7s Here are the headlines from the press release The 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. The new model is also the 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...The camera also 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. World’s First Full-Frame Camera with Full Pixel Read-out3 (without pixel binning) during Movie Shooting In video mode, the α7S can output 4K video4 at QFHD (3840x2160) to an optional external 3rd party 4K recorder, and 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. 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, 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. 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 (1280x720 @30p). The camera also 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.
