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 stills
The Fast Hybrid AF system combines speed and precision. With 759 focal plane phase-detection sensors and 425 contrast-detection points distributed across most of the image area, the α7S III quickly finds and tracks your subject throughout the frame.
Outstanding continuous shooting performance
Use your choice of mechanical or electronic shutter for continuous burst shooting, with AF/AE tracking, at up to 10fps0. Capture decisive moments with over 1000 frames of continuous uncompressed RAW shooting possible1.
Highly-sensitive AF for low-light focusing
AF algorithm advances have allowed the α7S III to achieve autofocus in lighting conditions as dim as EV-60, where subjects are barely even visible with the naked eye.
Still-image quality advances through new sensor and engine
The newly-developed image sensor and image processing engine deliver improvements in colour reproduction, particularly of skin tones, and texture depiction in still images.
New HEIF format and HLG image capture modes0
The HEIF image file format is supported, offering better image quality and greater compression efficiency than JPEG, plus 10-bit colour. High Dynamic Range still images can also be captured in HLG mode for viewing on compatible TVs.
