Sony Alpha a7S III Mirrorless Camera - The full-frame mirrorless camera is equipped with a back-illuminated 12.1MP Exmor R CMOS sensor and an improved processor compared to previous models. The camera delivers professional stills and movies with high performance full-frame sensor, including sensitivity with an extended ISO range of up to 409,600, a dynamic range of 15 stops, 4K 120p shooting, fast and reliable autofocus, and ultra-efficient stabilization. A mechanical or electronic burst shutter with AF / AE tracking enables continuous shooting at up to 10 frames per second. With uncompressed RAW burst shooting, over 1000 frames can be captured. The camera has an integrated 5-axis image stabilizer. The back-illuminated 12.1MP full-frame Exmor R CMOS sensor collects light more efficiently, with improved routing and signal optimization. This doubles the data read speed. Now you can capture high-quality images over the entire sensitivity range and use a dynamic range of 15 stops. The sensor is also equipped with phase detection autofocus in the focal area. In addition to the high-speed sensor, the camera uses the BIONZ XR processor, which is 8 times more powerful than previous processors. It provides high quality images. In addition, the responsiveness of the camera interface has been improved. Wide Area AF uses intelligent tracking and phase detection on the sensor. Precise, grippy AF and a high-quality E-mount lens deliver sharp images even when capturing moving subjects with shallow depth of field in 4K 120p. The Sony Alpha 7S III can shoot 4K video at 120 frames per second and records material in 10-bit color and 4: 2: 2 color subsampling. This provides flexible options for color grading, post-processing and image compositing. Besides Long GOP, All-Intra coding is now available. In this format, each frame is encoded independently of the others at speeds up to 600 Mbps, which allows you to shoot complex movements and record video on internal and external media, as well as simplify editing. The new XAVC HS recording format uses HEVC / H.265 encoding to deliver twice the compression efficiency of AVC / H.264 encoding, deliver superior picture quality and reduce file size. The camera has an extended ISO range of 80-409600 units, a standard 80-102400 units, and thanks to the latest light collection and output optimization, the 12.1 MP2 full-frame sensor provides low noise and allows shooting in extremely low light conditions. The HDMI Type A port provides 16-bit RAW output to external recorders. It uses XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K. The camera records proxy files at the same time. Both card slots support ultra-fast CFexpress Type A cards for high-speed writing and fast buffer emptying, and SDXC UHS-II cards. In addition, parallel and sequential recording functions are available.
