Sony a7S III
Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel back-illuminated Exmor R CMOS image sensor packs major innovations in light gathering, wiring and output optimization. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.
High ISO sensitivity
With an amazingly wide standard ISO range of 80–102400 (expandable to 40–409600 for stills), the α7S III offers incredible creative opportunities. The newly developed image sensor and image processing algorithms produce even cleaner images and more natural textures than the previous α7S II model, even when shooting in near total darkness.
Fast Hybrid AF for accuracy and tenacity
The wide-area AF uses intelligent tracking and on-sensor phase-detection covering most of the frame. The result is that every bit of supremely accurate and tenacious AF performance is extracted in combination with high-quality E-mount lenses, even when shooting moving subjects at shallow depths-of-field in 4K and at 120p frame rates
Real-time Eye AF for movies
Real-time Eye AF uses AI to ensure pinpoint focusing precision for eyes, with performance now improved by 30% on profile or partially obscured faces. Tenacious eye tracking lets you concentrate on composition even with a shallow focus depth.
New HEIF format and HLG image capture modes
The HEIF image file format is supported, offering better image quality and greater compression efficiency than JPEG, plus 10-bit color. High Dynamic Range still images can also be captured in HLG mode for viewing on compatible TVs.
