Sony introduces the RX1R III compact camera featuring a 61-megapixel full-frame back-illuminated CMOS sensor paired with a fixed Zeiss Sonnar T* 35mm F2 lens. The device employs an AI processing module that identifies subjects across people, animals, birds, insects, and vehicles while managing focus through 693 phase-detection points spanning 78 percent of the frame. Mechanical shutter performance reaches 1/4000s to 30s with electronic capabilities extending to 1/8000s, while ISO sensitivity operates from 100 to 32000 natively and expands between 50 and 102400. The camera delivers 15-stop dynamic range and offers step-crop shooting modes that alternate between 35mm, 50mm, and 70mm equivalents while maintaining 15 to 60 megapixels. Video recording capabilities encompass 4K at 30fps and Full HD at 120fps through XAVC S or XAVC SI formats, with autofocus functioning at negative 4 EV and wireless connectivity through Wi-Fi 802.11ac and Bluetooth 4.2.
