Rendering scenes in realistic detail. An advanced 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. The amazing technology achieves stunning processing speed. The 24.2-megapixel Exmor R CMOS sensor, now featuring a back-illuminated structure, is combined with the 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. 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. 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. 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. 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 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 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 mode. 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. 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, letting you capture decisive moments. Reliable AF down to EV-315 brightness. Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-315, 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-EA3.16 Eye AF revolutionizes portraiture with the a7 III, Eye AF can now be used with AF-C mode, for fast, effective eye detection/tracking performance when shooting stills. The easy maintenance of optimum focus on moving subjects can totally transform your portraiture.
