The Alpha 7S III features a newly developed 12.1-megapixel Full-frame Backside-illuminated (BSI) Exmor R CMOS sensor that delivers sensitivity, speed and superior images and movie. It takes full advantage of the large pixels and BSI copper wiring structure to more than double the sensitivity and readout speed. The results are astounding, with phenomenal low-light capability, up to 15+ stops of dynamic range4 and drastically reduced noise for ultra-sharp and clean images and 3x reduced rolling shutter. In addition, this new Exmor R sensor features Sony’s acclaimed fast hybrid autofocus with 759 phase detection AF points and 92% coverage. The high sensitivity also allows it to autofocus in light as low as EV-6.
A new BIONZ XR processing engine delivers 8x more processing power than previous models. It not only supports the high sensitivity and wide dynamic range that has become hallmarks of the “S” series, but also high-speed features such as real-time AF tracking and up to 10fps continuous shooting of more than 1000 RAW still images. This new BIONZ XR engine can process large volumes of data in real time, making full-frame readout without pixel binning possible in all recording modes, including 4K 120p All-I 10-bit 4:2:2. Whether shooting stills or movies, the Alpha 7S III offers overwhelming image quality with stress-free operation.
The Alpha 7S III builds on the legendary low-light performance synonymous with Sony’s ‘S’ series. The 12.1MP sensor is optimized for 4K with full-pixel readout and to make use of much larger individual pixels for maximum light gathering capabilities and low signal-to-noise ratio. Fewer pixels mean each individual pixel is larger than on other higher pixel-count full-frame sensors. The Alpha 7S III also employs Sony’s industry-leading Exmor R backside-illuminated CMOS image sensor technology for additional low light performance and to double the readout speed. Base ISO is lower than previous ‘S’ models, with a still and movie range from 80 to 102,400, expandable to 40 to 409,600 for stills and 80 to 409,600 for movies. Thanks to the high-sensitivity, Exxmor R sensor and fast processing, the dynamic range for movies is an impressively wide 15+ stops.
