Sony’s alpha 7S Mark III is the third iteration in the most video-focused of the company’s a7 series of full frame cameras. It’s essentially a native 4K camera with impressive video specs and a revised user interface. It can capture UHD 4K footage at up to 120p in 10-bit 4:2:2 encoding and promises 16-bit Raw video output.
The a7S III offers a series of new features such as 10-bit internal video and Raw video output but the changes go much deeper. Alongside a host of ergonomic improvements, which includes greater use of the touchscreen, Sony has significantly redesigned its menu system. The a7S III has a dual gain sensor and produces impressively low rolling shutter times.
