More Features

S-Log2 and S-Log3 with 10 bit 4:2:2 support

S-Log3 is designed for better reproduction of gradations from shadows to the mid-grey range (18% grey), enabling a dynamic range of up to 15 stops. The colours match makes colour grading easier in post-production editing, making it more convenient to use the α7S III along with other pro cameras.

HEVC codec with high compression efficiency

New XAVC HS format recording using the MPEG-H HEVC/H.265 codec roughly doubles the compression efficiency. Compared to a normal 4K XAVC S format, XAVC HS allows for detailed 10-bit video with 4:2:2 colour sampling at comparable or lower data rates, delivering even better image quality as well as manageable file sizes.

16-bit RAW data output

Facilitating improved image quality and more flexible and efficient editing in post-production, the camera supports 16-bit RAW data output to an external recorder via HDMI, for the first time in the α series. The output is full-frame 4264 x 2408 (16:9 aspect ratio) 16-bit data from the image sensor, with a choice of frame rates (60p/50p/30p/25p/24p).

Enhanced movie image quality

With the new image-processing engine, colours and textures of foliage and human skin can be more consistently reproduced without over-dependence on light sources. Gradation rendering has also been refined, for better-looking skin tones and highlight roll-off in portraits.

AF support in manual-focus mode

Autofocus support can be useful even when you're primarily using manual focus. For full AF speed, half-press the shutter button or press the AF-ON button. Alternatively, slower, more cinematic AF transitions can be achieved by initiating AF via the touch focus feature or Real-time Eye AF via a custom button assignment.

Enhanced audio quality

A digital audio interface is incorporated in the camera's Multi Interface (MI) Shoe, to facilitate cleaner, clearer audio recordings without loss of quality. The XLR-K3M XLR Adaptor Kit additionally provides the camera with 4-channel 24-bit digital audio recording capability.

Product Showcasing Videos


Designed for professionals, the α7S III builds on the strengths of the S series such as high sensitivity and wide dynamic range while providing pro features like enhanced AF, optical image stabilisation and 4K 120p28 recording. Incorporating a powerful new engine in its compact body, the camera delivers a wide range of visual experiences.
