Professional Grade Camera

The Sony Alpha 7S III is a professional grade camera that has been five years in the making and highly anticipated. With a focus on videography and cinematography, this camera is designed to meet the highest of demands. It features an entirely new image sensor and BIONZ XR image processor for a new stills and movie recording experience. You'll be amazed at the clarity of the images this camera produces, while the 4K, 120 fps and 240 fps FHD offer incredible video footage.

New improvements

The new full-frame 12.1 megapixel back-illuminated Exmor R CMOS sensor delivers incredibly high sensitivity and low noise. With huge improvements to light gathering, wiring and output optimisation, images are razor sharp. Additionally, the newly developed BIONZ XR image processing engine allows for 8x more processing power, delivering ultra-high-quality images quicker, resulting in superior still and video quality.

Incredible autofocus performance

As a result of the innovations, this in turn means that always-active pinpoint AF is constantly ready to deliver. Supporting focal plane phase-detection, this allows for an increase in stability and precision when shooting. This provides stunningly clear results that target your subject, even when recording 4K 120p or in slow motion. The camera has object, face and eye tracking capabilities for both humans and animals.

Versatile ISO

With an expanded ISO range of 80 - 409,600 (standard range 80 - 102,400), along with advanced light-gathering an output optimisation, low noise is easily achieved, even when shooting in almost complete darkness.

Full-frame 4K recording at 120p

Experience amazing 4K 120p video recording capabilities and shoot stunningly clear video. With full-pixel readout without binning, you are able to post-produce slow motion effects and achieve beautiful bokeh effects.

In terms of colour grading, the camera records with 10-bit-depth and 4:2:2 colour sampling when using either Long GOP or All Intra compression. This enables colours to be pushed further for a mor bold and true-to-life result, while HDR realism that features a natural gradation allows for more freedom when it comes time to edit.

High speed continuous shooting

Both the mechanical and electronic shutters are capable of 10 frames per second continuous shooting with AF/AE. To take it one step further, continuous shooting of over 1000 uncompressed RAW images is possible due to the increased buffer memory of the BIONZ XR processor and memory card writing speed.

High definition 9.44 million dot electronic viewfinder

Challenging the resolution of the human eye, the a7S III's resolution is the highest of its class. It boasts a 0.90x viewfinder magnification, 41° diagonal field of view and a 25mm high eyepoint that provides clear and low-distortion viewing.

Two memory card slots

Aside from being compatible with SDXC/SDHD cards supporting UHS-I and UHS-II speed classes, the memory card slots are also compatible with new CFexpress Type A cards.
