With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p1, fast and dependable autofocusing, and extra-strong image stabilisation, the α7S III again raises the bar for movie makers.Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel2 back-illuminated　Exmor RTM CMOS image sensor packs major innovations in light gathering, wiring and output optimisation. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop3 wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.Up to 8x more powerful4 BIONZ XRTM image processor
Along with the new sensor and its unprecedented speed, the BIONZ XR image processing engine has also been newly developed and packs up to 8x more processing power4. With a future-oriented architecture, it delivers high quality images faster for superlative still and video expression, as well as dramatically improved camera interface responsiveness.
