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 Sony α7S III again raises the bar for movie makers.
Large pixels deliver high sensitivity and low noise
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.
Up to 8x more powerful 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 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.
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.
16-bit RAW HDMI output
For demanding post-production workflows, 16-bit RAW output is available via HDMI connection to compatible external recorders while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and proxy files are simultaneously captured in-camera.
Two CFexpress Type A-compatible media slots
Both card slots support both ultra-fast CFexpress Type A cards, allowing high-bit rate recording and fast buffer clearance, and SDXC UHS-II cards. Parallel and Relay recording are also available.
The Sony a7s III is available for rent at Lorne Lapham here in Vancouver and we can ship Canada wide.
