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-megapixel4 Exmor R™ CMOS sensor, now featuring back-illuminated structure, is combined with the latest BIONZ X™ image processing engine and front-end LSI, and this combination achieves 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 camera’s 35mm 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 minimising noise to reveal fine details in every picture.
Reducing noise in high-resolution images
Up to 1.5-stop improvement5 in image quality
Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-2048006 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 and image deterioration.
Subtle gradation from shadow to highlight
Dynamic range of up to approx. 15 stops
Approx. 15-stop dynamic range7 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 colour reproduction
More accurate colour reproduction straight out of the camera
Colour reproduction performance is dramatically enhanced, giving subjects that you capture more natural colour that is faithful to how the colours 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 stabilisation
The latest high-precision stabilisation uses stabilisation 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 α9 and applying it optimally, so once the α7 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
Combining focal-plane phase-detection AF for excellent speed and tracking plus high-precision contrast-detection AF, Sony’s sophisticated Fast Hybrid AF can capture fast-moving subjects in razor-sharp images. This system advances performance to double AF speed.
4D FOCUS: Steadfast tracking
Enhanced AF tracking for swiftly moving subjects
The AF performance inherited from the α9 accounts for AF tracking with enhanced precision for continuous shooting of quick action. With faster image sensor readout, even complex subject motion can be tracked and sudden movements can be predicted with great precision, allowing you to capture decisive moments.
Reliable AF down to EV-314 brightness
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-314, for more reliable autofocus in dark scenes.
Focal-plane phase-detection AF supports A-mount lenses
693-point focal-plane phase-detection AF not only covers a wide area and responds instantly — it offers the benefits of high tracking performance even with an A-mount lens mounted via mount adaptor LA-EA3.
