Image sensor with double the readout speed

The back-illuminated full-frame Exmor R CMOS sensor, with 12.1 effective megapixels, boasts a readout speed up to twice as fast as that of the α7S II, along with high sensitivity and wide dynamic range. An advanced colour filter array boosts colour reproduction accuracy, while focal plane phase-detection AF enables substantial increases in autofocus stability and precision, all of which contribute to outstanding image quality.

High sensitivity, wide dynamic range

The full-frame 12.1-megapixel configuration enables high sensitivity with low noise throughout the camera's sensitivity range by optimising the output signal from the sensor. The standard ISO range is 80-102400, which is further expandable to 40-409600 (80-409600 for movies). The dynamic range is an impressively wide 15 stops, for beautiful, true-to-life images without blown highlights. Together, the camera's high sensitivity and wide dynamic range expand your creative freedom during shoots.

All-Intra internal recording

In addition to Long GOP inter-frame compression, the α7S III supports internal intra-frame (All-Intra) recording for the first time in an α-model body, where each frame is recorded independently at a high bitrate of up to 600Mbps. This can be useful for certain types of shoots as it allows maximum flexibility in post-production editing. 

Full-frame 4K recording at 120p plus revolutionised movie shooting

Full-frame 4K recording at 120fps with autofocus is possible thanks to the high-speed readout capabilities of the new image sensor working in tandem with the newly developed, powerful BIONZ XR processor. This high image-quality 4K, with full-pixel readout without binning, allows for clear post-produced slow motion (up to x5 slower than real time), as well as bokeh effects typical of full-frame cameras, all with smooth, high-precision autofocus. Despite the α7S III's compact size, it provides impressive scope for your creativity. 

Additionally, Real-time Tracking and Real-time Eye AF make movie-making much easier. Touch Tracking initiates subject tracking with an intuitive touch to the LCD monitor, processing data on colour, pattern (brightness), distance (depth) and facial information to keep your subject in steady focus. You can then concentrate more fully on composition, which can be especially useful when you're shooting solo or using a gimbal. Touch operations can be used to temporarily engage AF even when you're shooting manually.

Proxy recording for more efficient editing workflow

When shooting movies, low bit-rate HD proxy files can be recorded simultaneously with higher bit-rate formats such as XAVC S-I 4K, and these smaller proxy files can then be used for editing and previewing prior to final production delivery. This reduces computer load and allows faster and more efficient workflows. Proxy files can be captured in either 10-bit XAVC HS (1920 x 1080) or 8-bit XAVC S (1280 x 720).

Two CFexpress Type A-compatible media slots

The camera's two media slots are compatible with new CFexpress Type A cards as well as SDXC/SDHC cards supporting UHS-I and UHS-II speed classes. CFexpress Type A cards are the next standard for compact storage with fast write/read speeds suitable for both high-speed continuous still shooting and 4K movie recording at high bit rates. They are capable of quickly clearing camera buffers even when high volumes of still image and movie data are being generated.
