The Sony a7S III Mirrorless Camera redefines cinematic video performance, featuring a 12.1MP full-frame Exmor R BSI CMOS sensor. Known for its low-light prowess, this sensor delivers outstanding sensitivity, wide dynamic range (up to 15 stops), and minimal noise—perfect for capturing breathtaking 4K 120p video footage. With the power of the BIONZ XR processing engine, the a7S III offers up to 8x faster processing, enabling real-time autofocus tracking, superior image quality, and an impressive 10fps burst shooting speed.
One of its standout features is the 10-bit 4:2:2 internal video recording, which allows for highly detailed color gradation and smooth editing flexibility. This makes the a7S III ideal for professional videographers seeking the highest quality in their footage. The efficient XAVC HS format, using the MPEG-H HEVC/H.265 codec, doubles the recording efficiency compared to previous models, making the camera even more powerful.
The 759-point Fast Hybrid AF system, along with real-time Eye AF for birds and continuous shooting up to 10fps, ensures you’ll capture every moment with precision. Whether you’re shooting high-speed action or delicate details, the camera delivers outstanding focus and clarity.
In addition, the a7S III features 5-axis sensor-shift image stabilization for steady shots even in challenging conditions. The camera includes dual CFexpress Type A and SD card slots for enhanced workflow and storage. The 9.44 million-dot OLED electronic viewfinder and a 3.0″ vari-angle touchscreen allow for precise framing and easy navigation.
With an extended ISO range of 40–409,600 and an unlimited recording limit, the a7S III is designed to handle demanding shooting situations, from dark environments to fast-paced action scenes.
