The latest addition to Sony's RX10 fixed-lens long-zoom series of cameras, the Cyber-shot DSC-RX10 III replaces the 24-200mm (equivalent) zoom lens in the RX10 II with a new Zeiss Vario-Sonnar T* 8.8-220mm f/2.4-4 lens that covers a wide, 25x optical zoom range equivalent to 24-600mm in 35mm format.
