Sony a7S III alpha 7S III Full-Frame Mirrorless Camera

Sony a7S III Mirrorless Camera

Incorporating a powerful new engine in its compact body, the a7S III builds on the strengths of the S series such as high sensitivity and wide dynamic range, while providing pro features like enhanced AF, optical image stabilisation and 4K 120p recording.

New image sensor with double the readout speed

The newly developed back-illuminated full-frame Exmor RTM CMOS sensor, with 12.1 effective megapixels, boasts a readout speed up to twice as fast as that of the a7S 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.

New image-processing engine with up to 8x the processing performance

The BIONZ XRTM image-processing engine boasts a performance level up to eight times that of the previous processor, minimising latency while markedly improving real-time processing capabilities for both movies and stills. The engine performs real-time processing of AF, image recognition and image-quality adjustments, while also handling data transfer, user interface and other camera operations.

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.
