a7 III Perfection for all. Everything you need. Capture the peaks of more decisive moments with the a7 III from Sony packing newly developed back-illuminated full-frame CMOS sensor and other advanced imaging innovations, high-speed response, ease of operation, and reliable durability that are ready for various shooting needs. Rendering scenes in realistic detail A newly developed back-illuminated image sensor and evolved image processing system fulfil 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-megapixel5 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 faster6 and a data processing capability that is 1.8 times higher6. Exmor R CMOS sensor and image processor Back-illuminated structure Reducing noise in high-resolution images Up to 1.5-stop improvement6 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 and image deterioration. Subtle gradation from shadow to highlight Dynamic range of up to approx. 15 stops Approx. 15-stop dynamic range8 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 stabilization The latest high-precision stabilization uses stabilization unit and gyro sensors and algorithms to achieve a 5.0-step9 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 RAW10 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 RAW10 data output, even when in silent or continuous shooting mode11. 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, so 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: 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 a9 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.
