Introducing the Alpha 7S III a new milestone in sensitivity, speed and image supremacy. Featuring an all-new 12.1MP backside illuminated full-frame sensor with twice the readout speed for ultra-clean low-light images up to ISO 409,600 with 15+ stops dynamic range and 3x reduction in rolling shutter, plus Sony’s acclaimed fast hybrid autofocus with 759 phase detection AF points. A new BIONZ XR processing engine deliver 8x more processing power for up to 120p 4K 10-bit 4:2:2 and full pixel readout in all recording modes.
With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p, fast and dependable autofocusing, and extra-strong image stabilization, the a7S III again raises the bar for movie makers.
The new full-frame 12.1-megapixel back-illuminated Exmor RTM 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.
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 power. 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.
The new Exmor R full-frame image sensor and revolutionary BIONZ XR image-processing engine deliver always-active pinpoint AF for astonishing detail in both space and time, and stunning 4K movies even at 120 frames per second or in slow motion. With the resolution and depth of field only possible from a full-frame sensor, the results are spectacular.
Record right on the camera with the amazing richness of 10-bit depth and 4:2:2 color sampling, for far greater flexibility in image grading, post-processing and compositing.
The renowned sensitivity of the series scales new heights, with an expanded ISO range for movies from 80 to a remarkable 409600 (standard range 80102400). With advanced light-gathering and output optimization, the 12.1-megapixel full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near-total darkness.
