The expected and highly filtered Sony Alpha 7S III is official. After the presentations of its most direct competitors, such as Panasonic and Canon, Sony had to move tab and launch a camera that surprised in the vast majority of its sections, but especially on video. And it has not disappointed. The new Alpha 7S III offers 4K video recording up to 120 fps and 10: 4: 2: 2, a dynamic range of more than 15 steps, improved AF performance and much more. Let’s get to know its characteristics better.
Sony Alpha 7S III, the queen of the night
The new Alpha 7S III has been completely redesigned to offer better video and photography performance. Count with one new 12.1MP 35mm full-frame Exmor R CMOS image sensor Backlit that reduces rolling shutter up to three times and uses advanced light gathering techniques to ensure high sensitivity with low noise. This will allow us to work in low light situations without the need for large external lighting settings.
This new image sensor includes a Focal plane phase detection AF system for the first time in an S series camera. The Alpha 7S III also includes a new BIONZ XR image processor It provides up to eight times more processing power.
The new Alpha 7S III image sensor and BIONZ XR image processor have achieved reducing the minimum ISO to 80, which translates to a normal range of 80-102,400 (expandable to 80-409,600 for video and 40-409,600 for photography) to provide a more flexible ISO and wide dynamic range with low noise at all settings. It offers improved image quality in approximately 1 step of noise reduction in the medium and high sensitivity ranges.
As for the focus, Alpha 7S III includes Fast Hybrid AF, which combines phase detection AF and contrast detection. This allows you to track subjects over a wide area with greater speed, precision and smoothness, even when using a narrow depth of field. In addition, for environments with a lot of movement, the camera has Real-time Tracking and Real-time Eye AF to maintain a constant focus on the desired subject. In fact, the eye focus system has improved its detection performance by 30% over the previous system, thanks to the new image processor.
4K video recording up to 120 fps
The Sony Alpha 7S III offers 4K in-camera recording at up to 120 frames per second, 10-bit depth, and 4: 2: 2 color sampling. The new camera offers various advanced movie recording modes, such as All-intra encoding and MPEG-H HEVC / H.265 (XAVC HS). In addition, it makes it easy to integrate video recordings with other professional camcorders by providing three color gamut settings: S-Gamut, S-Gamut3, and S-Gamut3.Cine.
In addition to S-Log3 gamma curves, the Alpha 7S III supports an HLG (Hybrid Log-Gamma) image profile, with minimal post-production. The Alpha 7S III also allows output up to 4K 60p 16-bit RAW to an external recorder via HDMI Type A, to offer greater postproduction flexibility.
On the other hand, Sony has updated the design of the Alpha 7S III to ensure effective heat dissipation. This is capable, according to the manufacturer, of minimizing camera overheating even during 4K 60p 10-bit 4: 2: 2 video recordings of an hour or more.
Price and availability
The Sony Alpha 7S III was a highly anticipated camera, since there were many of us who wanted to see how Sony improved the magnificent Sony A7 III. The Japanese manufacturer has listened to its users and has modified and added practically everything they were looking for. The A7S III has up to folding screen, so much in demand for years.
