Sony A7iii 24MP UHD 4K Mirrorless Digital Camera
Back-illuminated 24.2MP3 full-frame sensor
The 35 mm full-frame Exmor R™ CMOS image sensor features 24.2-megapixel3 resolution, back illumination, and gapless on-chip lens design for extraordinary sensitivity and dynamic range. Two times faster4 data readout speed is achieved through copper wires and front-end LSI.
Entirely enhanced image processing system
A combination of new-generation image processing system and a new sensor achieves an up to 1.5-stop improvement4 in image quality. A wide ISO sensitivity range of up to ISO 51200 is standard, and approx. up to 15-stop5 dynamic range at low sensitivity settings is achieved. Upgraded Detail Reproduction and Area-specific Noise Reduction combine to suppress noise and maintain a sense of high overall resolution. Color reproduction, especially of skin and nature scenes, has also been dramatically improved. The α7 III also supports 14-bit RAW output6 even during silent shooting/continuous shooting7.
Wider, faster, more steadfast AF performance
An evolved image processing system and α9 camera AF algorithms optimized for the α7 III improve AF speed, precision, and tracking performance. 693 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. AF speed up to twice as fast8 and more precise AF tracking performance let you capture and maintain focus on a quickly moving subject in unpredictable motion. The α7 III also autofocuses reliably down to EV-3 brightness9
Focal-plane phase-detection AF supports A-mount lenses10
Phase-detection AF can operate even when an A-mount lens10 is mounted to the α7 III via an LA-EA3 adaptor. The 693-point focal-plane phase-detection AF system provides wide-area coverage, fast response, and high-performance tracking.
Always keep the eye in focus
Eye AF newly supports AF-C mode with greater precision that dramatically enhances portrait shooting, plus higher AF speed that makes it easier to shoot a portrait of a moving subject, even if the subject looks down and away from the camera or is backlit with face in partial darkness. The Sony A7iii supports Eye AF for A-mount lenses11 mounted via an adaptor.
