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.
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. 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’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.
