The mark-III version of the RX100, the Cyber-shot DSC-RX100 III, was released in June 2014. The camera had a new Bionz X processor and a new Zeiss Vario-Sonnar T* lens (24-70mm, f1.8-2.8) giving a wider angle of view. Unlike its predecessor, the RX100 II, it does not have Sony's multi-interface hotshoe, but includes a pop-up OLED electronic viewfinder. The DSC-RX100 III has customizable functions. The viewfinder and rear LCD can be set to different displays. The RX100 III can be set manually with shutter speed and aperture fixed, but with Auto ISO (sensitivity) giving the correct metered exposure. (wikipedia)
