The 20.1MP 1.0-type stacked sensor, bright zoom lens and BIONZ X processor combine to produce a good image, whether shooting stills or video at up to 4K quality. Furthermore, by pairing the convenience of an ultra-telephoto lens with an innovative stacked CMOS image sensor, the RX10 III delivers new imaging experiences such as super slow-motion video capture at up to 1000 fps all the way up close to ultra-telephoto range. It benefits from an extremely accurate AF that focuses in just 0.09 seconds.
The newly designed optics in the camera include eight ED glass elements including one super ED glass element and two ED aspherical lenses . The newly developed optical design contains the sophisticated advanced aspherical (AA) lens and delivers above average imaging performance while keeping the lens unit itself small. Additionally, with a minimum focusing distance of 72cm at a fully extended 600mm (0.49x maximum magnification), the new lens is capable of producing amazingly detailed tele-macro images. The ZEISS T Coating minimises flare and ghosting that often affects image quality in adverse lighting conditions.
The aperture unit has nine blades that are designed to create a near-perfect circle in the F2.4 to F11 aperture range which enables soft, beautiful bokeh expression. The Optical SteadyShot algorithm has been optimised for the lens design of the RX10 III and delivers up to 4.5 stops image stabilisation for protection against camera shake, even when shooting from the hand in ultra-telephoto or low-light conditions.
