For visual trailblazers

With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p2, fast and dependable autofocusing, and extra-strong image stabilization, the α7S III again raises the bar for movie makers.

 

 

Large pixels deliver high sensitivity and low noise

The new full-frame 12.1-megapixel3 back-illuminated Exmor RTM CMOS image sensor packs major innovations in light gathering, wiring and output optimization. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop4 wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.


 

Up to 8x more powerful5 BIONZ XRTM image processor

Along with the new sensor and its unprecedented speed, the BIONZ XR image processing engine has also been newly developed and packs up to 8x more processing power5. With a future-oriented architecture, it delivers high-quality images faster for superlative still and video expression, as well as dramatically improved camera interface responsiveness.

 

 

Stunning AF performance even at 4K 120p2

The new Exmor R full-frame image sensor and revolutionary BIONZ XR image processing engine deliver always-active pinpoint AF for astonishing detail in both space and time, and stunning 4K movies even at 120 frames per second2 or in slow motion. With the resolution and depth of field only possible from a full-frame sensor, the results are spectacular.

Sony Alpha A7S III - Higher quality, smaller file size

Superior quality and smaller files with XAVC HS

The new 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 sizes6.

 

 

Sony's Renowned sensitivity delivers expanded ISO 409600

The renowned sensitivity of the series scales new heights, with an expanded ISO range for movies from 80 to a remarkable 409600 (standard range 80—102400). With advanced light-gathering and output optimization, the 12.1-megapixel3 full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness.

Sony Alpha A7S III - 16-Bit RAW HDMI Output

16-bit RAW HDMI output

For demanding post-production workflows, 16-bit RAW output7 is available via HDMI connection to compatible external recorders8 while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and proxy files are simultaneously captured in-camera.

Sony Alpha A7S III - Efficient Editing

Efficient editing through proxy recording

While recording high-bitrate 4K movies, HD proxies (in 8 or 10-bit depth) can be generated in-camera9. Editing the smaller proxy files reduces computer load and speeds up workflow prior to final 4K delivery.

 

 

Fast Hybrid AF for accuracy and tenacity

The wide-area AF uses intelligent tracking and on-sensor phase-detection covering most of the frame. The result is that every bit of supremely accurate and tenacious AF performance is extracted in combination with high-quality E-mount lenses, even when shooting moving subjects at shallow depths-of-field in 4K and at 120p frame rates2.
