a7S

  • The innovative a7S camera features a newly developed, 12.2 effective megapixel 35mm CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 409600 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 is also equipped with the same high-precision Fast Intelligent AF system as the a7R camera, with drastically improved low-light AF sensitivity that can go as low as -4EV.
