Product Description

Sony Alpha 7S III Full-frame Mirrorless Camera Body

The Sony Alpha 7S III sets a new benchmark for full-frame mirrorless cameras, particularly renowned for its exceptional video capabilities, sensitivity, and speed. Featuring a revamped 12.1MP Exmor RS CMOS sensor and the powerful BIONZ XR image processor, it delivers remarkable performance with reduced noise, faster processing, and an expanded dynamic range.

12.1MP Exmor RS BSI CMOS Sensor and BIONZ XR Processor The camera’s back-illuminated full-frame Exmor RS CMOS sensor enhances clarity and sensitivity, offering an impressive ISO range of 80-102400 (expandable to 40-409600). Paired with the BIONZ XR processor, it achieves up to 2x faster readout speeds compared to its predecessor, ensuring minimal rolling shutter and enabling 10fps continuous shooting with up to 1000 uncompressed RAW files.

Video Recording Capture UHD 4K video at up to 120fps using full-pixel readout without pixel binning. Internal 10-bit 4:2:2 sampling is available across all recording modes, with 16-bit RAW output via HDMI for maximum flexibility in post-production. New codecs include XAVC HS for efficient H.265 encoding, and XAVC S-I for intraframe recording up to 600 Mb/s.

Autofocus and Image Stabilization The Fast Hybrid AF system boasts 759 phase-detection and 425 contrast-detection AF points covering 92% of the frame, ensuring rapid and precise focusing even in low-light conditions down to -6 EV. Real-time Eye AF and AI-based subject tracking enhance accuracy for both stills and video. The 5-axis SteadyShot INSIDE stabilization compensates for camera shake up to 5.5 stops, supporting stable handheld shooting.

Body Design and Connectivity Equipped with a high-resolution 9.44m-dot OLED Tru-Finder EVF and a vari-angle 3.0" touchscreen LCD, the A7S III offers versatile shooting angles and intuitive control. It features a robust magnesium alloy body with improved heat dissipation for extended recording times. Connectivity options include USB Type-C, full-size HDMI, headphone and microphone ports, and dual-band Wi-Fi for remote operation and file transfer.
