The Sony A7S III is a full-frame mirrorless powerhouse built for professional video and extreme low light. Its 12.1-megapixel back-illuminated Exmor R sensor and BIONZ XR processor deliver clean footage across an enormous ISO range with 15-plus stops of dynamic range.

It records 4K at up to 120p in 10-bit 4:2:2, with All-Intra encoding, dual CFexpress Type A slots and effective heat management for long takes. A 9.44-million-dot viewfinder and side-opening vari-angle screen make it a joy to operate.

For filmmakers and hybrid shooters who work in the dark, the A7S III sets the standard.
