Real-time Tracking Autofocus
For a first in an “S” series, the Alpha 7S III supports focal plane phase-detection. This enables a substantial increase in stability and precision when using autofocus, and importantly introduces the incredible abilities of Real-time Tracking Autofocus for both stills and movie mode. Object, and face and eye tracking is now available for both humans and animals.
15 stops Dynamic Range in movie mode
The Alpha 7S III, thanks to the improvements for both image sensor and image processor, now has the ability to record 15 stops of dynamic range in movie mode when shooting S-Log3 Gamma. 15 stops delivers significantly smoother gradation from highlights...

The Alpha 7S III, thanks to the improvements for both image sensor and image processor, now has the ability to record 15 stops of dynamic range in movie mode when shooting S-Log3 Gamma. 15 stops delivers significantly smoother gradation from highlights to shadows within a scene, retaining greater details and reproducing fine changes in texture.
Imagination in Motion
- 12.1 MP Exmor R Full Frame BSI CMOS image sensor
- Real-Time Tracking face and eye Autofocus for Movies and Stills
- 10-bit 4:2:2 colour sampling during internal video recording
- No recording time limits in all movie modes and improved heat dissipation allowing 4K60P video recording for over an hour*
RGB Chroma Subsampling
Powered by the BIONZ XR image processor, the Alpha 7S III offers chroma sub-sampling at the highest bit-depth seen on an α camera. 4:2:2 colour sampling collects fine colour details and at 10-bit delivers extraordinary realism to every scene. Thanks to the improved colour sampling, the Alpha 7S III supports the current industry standard HLG formats of BT.2020 and BT.2100 to deliver instant HDR content.
Video Recording Format - All-Intra
For the first time in an α series body, the Alpha 7S III introduces the XAVC S-I recording format for video which supports internal intra-frame (All-I) recording, allowing internal 4K recording at bit-rates up to 600 Mbps. The ability to capture this incredible amount of video data unlocks a wealth of post-production benefits while editing and colour grading the footage.
16-bit RAW recording
RAW video recording has become an increasing demand for ILC cameras. Supported by the HDMI 2.0 Type A, the Alpha 7S III can output RAW footage at an incredible 16-bit colour depth. 16-bit RAW footage offers greater colour and tonal reproduction in post-production when colour grading the footage. Such rich detail allows for unmatched artistic expression.
CFexpress Type A media slots
The upper (Slot 1) and lower (Slot 2) media slots both support UHS-I and UHS-II SDXC/SDHC cards as well as the all new CFexpress Type A cards for higher overall capacity and faster read/write speeds. CFexpress Type A cards are ideally suited to high-speed continuous still shooting as well as 4K movie recording at high bit rates, providing next-generation write speeds of still image and movie data.
