The Sony α7S III is a mirrorless full frame interchangeable lens camera.

Its full frame captures high-sensitivity and low noise images and records up to 12o fps at 4K videos with 15 stops, AF and image stabilizer.

10-bit 4:2:2 recording

The Alpha A7S III records right on the camera with 10-bit depth and 4:2:2 color sampling.

All-Intra encoding available

As well as Long GOP, All-Intra encoding is now provided.

This encodes every frame independently at bitrates up to 600Mbps, to capture complex motions more accurately for recording on either internal or external media, and allow more efficient editing workflows.

Superior quality and smaller files with XAVC HS

The XAVC HS recording format uses HEVC/H.265 encoding to achieve twice the compression efficiency of AVC/H.264 encoding, for superior image quality and smaller file sizes.

S-Log3 gamma, S-Gamut3.Cine gamut

The S-Log3 gamma curve and S-Gamut3.Cine color gamut, shared with pro camcorders, provide wider dynamic range and easier color matching for smoother post-production workflows.

Expanded ISO 409600 sensitivity

The sensitivity has an expanded ISO range for movies from 80 to a remarkable 409600 (standard range 80 – 102400).

With advanced light-gathering and output optimisation, the 12.1-megapixel full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness.

16-bit RAW HDMI output

For demanding post-production workflows, 16-bit RAW output is available via HDMI connection to compatible external recorders while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and proxy files are simultaneously captured in-camera.
