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 Sony Alpha 7S III Full-frame Interchangeable Mirrorless Digital Camera Body again raises the bar for movie makers.

Exmor CMOS Sensor

The Alpha 7S III features a newly developed 12.1-megapixel Full-frame Backside-illuminated (BSI) Exmor R CMOS sensor that delivers sensitivity, speed, and superior images and movies. It takes full advantage of the large pixels and BSI copper wiring structure to more than double the sensitivity and readout speed2. In addition, this new Exmor R sensor features Sony’s acclaimed fast hybrid autofocus with 759 phase-detection AF points and 92 percent coverage. The high sensitivity also allows it to autofocus in light as low as EV-611.

New BIONZ XR Processing Engine Delivers 8x More Processing Power

A new BIONZ XR processing engine delivers 8x more processing power than previous models. It not only supports the high sensitivity and wide dynamic range that has become hallmarks of the S series but also high-speed features such as real-time AF tracking and up to 10fps continuous shooting of more than 1000 RAW still.

Low Noise Images with ISO up to 409,6003 and 15+Stop Dynamic Range

The Alpha 7S III builds on the legendary low-light performance synonymous with Sony’s S series. The 12.1MP1 sensor is optimized for 4K with full-pixel readout and makes use of much larger individual pixels for maximum light-gathering capabilities and low signal-to-noise ratio.

10bits 4:2:2 Video Reaches New Levels of Realism

The α7S III can record 10-bit 4:2:2 video internally when using Long GOP or All Intra compression, making it possible to grade for fuller, more natural gradations while generally providing greater editing freedom. The maximum frame rate when recording full-frame 4K is 120p5.

Efficient MPEG-H HEVC/H.265 Coding

In addition to Sony’s common XAVC S (MPEG-4 AVC/H.264) codec found on current models, the α7S III adds XAVC HS format recording21 using the MPEG-H HEVC/H.265 codec for approximately twice the efficiency of XAVC S.

16bits RAW Output for Movie

The α7S III is capable of 16-bit RAW output up to 4K 60p to an external device6 via HDMI, to answer the increasing demand for RAW recording for applications that demand the highest quality and post-production flexibility provided by RAW output.

Fast Hybrid AF in All Modes

The α7S III incorporates Sony’s highly acclaimed fast hybrid AF in all modes for both still and movie shooting.

Effective Heat Dissipation

The heat buildup from processing large volumes of data when recording high-bitrate, high-resolution 4K 60p and 120p5 movies can plague other systems, but not the Alpha 7S III.

Two CFexpress Type A-Compatible Media Slots

Dual card slots, both compatible with CFexpress type A and SDXC/SDHC.

Vari-Angle LCD Monitor for Comfortable Movie Shooting

3-Inch Flip-out, vari-angle LCD monitor with touch menu and controls.

9.44 Million-Dot High-Definition Electronic Viewfinder

World’s first 9.44M8 dot 0.64-inch QXGA OLED eye-level viewfinder.

Advanced AF Transition and Sensitivity Settings

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.

Digital Audio Interface for Superior Sound

The camera’s Multi Interface Shoe allows for MI shoe microphones and accessories to be attached and features a built-in Digital Audio Interface for superb audio quality.
