Sony A7S III features optimized video, sensitivity, speed and also raises the bar for what a full-frame mirrorless camera is capable of. A revised 12.1MP Exmor R BSI CMOS sensor and updated BIONZ XR image processor offer faster performance, improved noise reduction, and a wider dynamic range, along with UHD 4K 120p video recording and internal 10-bit 4:2:2 sampling. The updated sensor design also yields 2x faster readout speeds than previous generations, and greatly reduces rolling shutter by 3x and up to 8x faster processing and overall camera handling. The Sony A7S 3 sensor and processor combination also helps to achieve a wide dynamic range, of up to approximately 14 stops for stills and 15 stops for video, and 10 fps continuous shooting for up to 1000 uncompressed raw files for stills.
