Description
The Sony A7S III is a full-frame mirrorless still and video camera featuring a new 12.1 MP back-illuminated Exmor R sensor and BIONZ XR image processor for incredible image quality and speed. Film makers can shoot pro quality footage at up to 4K/120p or 4K/60p without crop with fast and precise autofocus. The new BIONZ XR processor powers super-fast 0.02 autofocus and 40-409600 ISO (expanded) range for exceptional results in low-light photography and video (80-409600 for video). In-body 5-axis image stabiliser is included to keep handheld photos and videos steady. The vari-angle 3-inch LCD now has touch operation for the newly revised menu layout. The alpha a7S III also adds improved dust and moisture resistance so you can work in all weathers. The camera body is highly durable thanks to full the magnesium-alloy construction. We love this camera for its exceptional video capability and low light performance.
