New CMOS sensor and processing engine
A new 12.1 megapixel back-illuminated CMOS image sensor delivers enhanced hallmark features of the S series; high sensitivity, low noise, and wide dynamic range.
The new BIONZ XR processing engine provides up to eight times more processing power compared to the BIONZ X. This means colour reproduction is more realistic, AF and AE is faster, and the camera has the ability to process large volumes of data in real time, making full-frame readout without pixel binning possible in all recording modes, including 4K recording at 120p.
Unprecedented movie recording performance
In-camera 4K recording at up to 120 frames per second* for extraordinarily smooth slow-motion imagery. In addition to supporting 4:2:2 10-bit recording, this feature can be used with efficient Long GOP inter-frame compression or high-quality Intra (All-I) intra-frame compression.
Now with the ability to record 15 stops of dynamic range in movie mode when shooting S-Log3 Gamma, providing significantly smoother gradation from highlights to shadows within a scene, retaining greater details and reproducing fine changes in texture.
Supported by the HDMI 2.0 Type A, the Alpha 7S III can output RAW footage at an incredible 16-bit colour depth for greater colour and tonal reproduction in post-production.*With 10% image crop
Real-time Tracking Autofocus
For a first in the S series, the Alpha 7S III supports focal plane phase-detection. Focus is precisely and smoothly maintained over a wide area for all movie recording modes including 4K 120p. Importantly, it introduces the incredible abilities of Sony's industry leading Real-time Tracking Autofocus for both stills and movie mode.
Improved heat management
This camera has been redesigned from the ground up to ensure effective heat dissipation while maintaining a compact body size. The newly developed heat dissipating structure makes it possible to record 4K 60p 10-bit 4:2:2 video continuously for more than one hour**Sony test conditions when Auto Power Off temperatures is set to high. Under normal temperature (25 degrees Celsius).
World’s first* support for CFexpress Type-A memory cards
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 and 4K movie recording at high bit rates, providing next-generation read/write speeds of still image and movie data.*As of July 2020 product announcement.
