Back-illuminated 24.2MP1 full-frame sensor
The 35mm full-frame Exmor R™ CMOS image sensor features 24.2-megapixel1 resolution, back illumination, and gapless on-chip lens design for extraordinary sensitivity and dynamic range. Two times faster2 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 improvement2 in image quality. A wide ISO sensitivity range of up to ISO 51200 is standard, and approx. up to 15-stop3 dynamic range at low sensitivity settings is realised. Upgraded Detail Reproduction and Area-specific Noise Reduction join to suppress noise and maintain a sense of high overall resolution. Colour reproduction, especially of skin and nature scenes, has also been dramatically improved. The α7 III also supports 14-bit RAW output4 even during silent shooting/continuous shooting5.
Wider, faster, more steadfast AF performance
An evolved image processing system and α9 camera AF algorithms optimised 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 improved by up to twice6 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 brightness7.
