Gain control of expressive freedom
With outstanding imaging capability and high-speed performance contained in a compact body, the a7 III gives you the power, precision and flexibility to capture once-in-a-lifetime moments just as you like.
Rendering scenes in realistic detail
A newly developed back-illuminated image sensor and evolved image processing system fulfill various shooting needs with high-quality imaging capabilities that you would expect only of a full-frame camera.
Newly developed sensor, evolved image processor
The latest technology achieves stunning processing speed
A new version of the 24.2-megapixel Exmor R CMOS sensor, now featuring a back-illuminated structure, is combined with the latest BIONZ X image processing engine and front-end LSI and this combination achieves a data readout speed that is two times faster and data processing capability that is 1.8 times higher.
Back-illuminated full-frame sensor
Higher sensitivity and readout speed
The 35-mm full-frame CMOS image sensor with back-illuminated structure enhances light collection efficiency, expands circuitry scale, and, with the help of a copper wiring layer that contributes to quicker data transfer, outputs data at very high speed, while minimizing noise to reveal fine details in every picture.
Reducing noise in high-resolution images
Up to 1.5-stop improvement in image quality
Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-2048007 for stills), while Detail Reproduction and Area-specific Noise Reduction technologies maintain image details and cut noise. With highly effective performance in mid-to-high sensitivity ranges, you can shoot at high ISO with no concerns about noise or image deterioration.
Subtle gradation from shadow to highlight
Dynamic range of up to approx. 15 stops
Approx. 15-stop dynamic range at low-sensitivity settings is achieved, thanks to a revamped CMOS sensor and image processor that provide for smooth gradation from shadow to highlight. This gives you greater freedom of creative imaging.
