The Sony 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 range 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-611.

8x More Processing Power

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 10 fps continuous shooting of more than 1000 RAW still images. The BIONZ XR engine can process large volumes of data in real time, making full-frame readout without pixel binning possible in all recording modes. Whether shooting stills or movies, the Alpha 7S III offers overwhelming image quality with stress-free operation.

10-bit 4:2:2 Video

The a7S III can record 10-bit 4:2:2 video internally when using Long GOP or All-I compression, making it possible to grade for fuller, more natural gradations while generally providing greater editing freedom. Maximum frame rate when recording full-frame 4K is 120p.

Low-Light and 15+ Stops Dynamic Range

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. 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, this sensor and fast processing, the dynamic range for movies is an impressively wide 15+ stops.

High Speed for Slow Motion

The Alpha 7S III offers several in-camera 4K recording modes to match your creative need and desired format. 4K resolution at up to 120 frames per second delivers extraordinarily smooth 5x (max.) slow-motion imagery. In addition to supporting 10-bit 4:2:2 recording, this feature can be used with efficient inter-frame (Long GOP) compression or high-quality All-I compression. A maximum bit rate of 1200 Mbps (4:2:2 10-bit, H.264, All-I) delivers supreme image quality when directly replaying movies in slow or quick motion in the S&Q mode. Up to 10x slow motion with Full HD resolution is possible at 240 fps (24p recording), providing fresh perspectives on dynamic sports and other types of action.

All Intra (for XAVC S-I Recording)

In addition to the Long GOP inter-frame compression used in previous models, the a7S III supports All-I recording for the first time in an a body, allowing internal 4K recording at bitrates up to 1200 Mbps. Intra-frame recording provides extra margin for post production and still image extraction when needed.

Sony FE 50mm f/1.8 Prime Lens

The lightweight Sony FE 50mm f/1.8 prime lens delivers an outstanding blend of performance, compactness and value, making it a perfect choice for hobbyist photographers and videographers. Its optical design features an aspherical element that effectively compensates for all forms of aberration, resulting in beautiful, crisp imagery. Additionally, the lens has a circular aperture with a maximum of f/1.8, producing beautiful ‘bokeh’ in images that allows the subject to stand out against a smoothly defocused background.
