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.
Faithful color reproduction
More accurate color reproduction straight out of the camera
Color reproduction performance is dramatically enhanced, giving subjects that you capture more natural color that is faithful to how the colors look in real life. Skin tones in portraits, blue skies in landscapes and vivid hues in still life images look very realistic as a result.
Steadier shots with 5-axis stabilization
The latest high-precision stabilization uses stabilization unit and gyro sensors and algorithms to achieve a 5.0-step shutter speed advantage in a system that compensates five types of camera shake with a wide range of lenses and delivers excellent performance.
14-bit RAW output for rich gradations
For smoother, more natural gradation, the latest BIONZ X image processor and front-end LSI process image signals in 16-bit form. This processor also allows 14-bit RAW data output, even when in silent or continuous shooting mode.
Take aim with high AF performance
4D FOCUS-AF performance evolves
AF performance is improved using the same AF advancements as in the a9 and applying it optimally. Once the a7 III captures such unpredictably moving subjects as dancers, boxers and wild animals in action, it won't easily let them go.
4D FOCUS: Stunning wide coverage
693. Remarkable number of phase-detection AF points
This camera features 693 phase-detection AF points covering approx. 93% of image area, plus 425 densely positioned contrast-detection AF points to improve focus.
4D FOCUS: Fast AF speed
Up to two times faster AF performance
