Cyber-shot DSC-RX100 (original). The original RX100 was named as the  "European Advanced Compact Camera for 2012–2013"  by the European Imaging and Sound Association (EISA) and one of the 'Best Inventions of 2012' by "TIME". Since then, Sony has introduced new RX100 models almost one per year. Cyber-shot DSC-RX100 II. In June 2013, Sony unveiled a new edition of the camera, called DSC-RX100 II (model number DSC-RX100M2, also referred to as "RX100 Mark 2"). New features included: Hasselblad Stellar and Stellar  II. On 23 July 2013, Swedish luxury camera manufacturer Hasselblad announced the 'Stellar', a compact camera based on the DSC-RX100, incorporating a wooden or carbon grip. On 1 November 2013, Hasselblad announced another three cosmetic variants of the camera, named the Stellar Special Edition. On 26 November 2014, Hasselblad announced the Stellar II based on the DSC-RX100M2. Cyber-shot DSC-RX100 III. The mark-III version of the RX100, the Cyber-shot DSC-RX100 III (model number DSC-RX100M3), was released in June 2014. The camera had a new Bionz X processor, as used in the Sony Alpha  77 II, and a new Zeiss Vario-Sonnar T* lens (24-70mm (35mm equivalent), 1.8-2.8) giving a wider angle of view (while curtailing the maximum equivalent focal length from 100mm to 70mm). Unlike its predecessor, the RX100 II, it does not have Sony's multi-interface hotshoe (limiting flash photography to the small built-in unit), but includes a pop-up OLED electronic viewfinder (EVF). 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. Cyber-shot DSC-RX100 IV. In June 2015, Sony released the Cyber-shot DSC-RX100 IV, the mark-IV version of the RX-100. Like its predecessors, it has the same 1-inch 20.2 megapixel CMOS sensor and ISO levels 12800. The RX-100 MARK-IV can now record 4K video in XAVC-S format with frame rates up to 24, 25, and 30 fps. However, due to extreme write speed and processing power, it can only record 5-minute 4K shots to prevent any serious damage to the  camera. It also features Slow-mo video recording and can capture up to 960 fps for NTSC mode and 1000 fps for PAL mode. Cyber-shot DSC-RX100 V. On October 6, 2016, Sony announced the RX100 V. In this update, Sony improved the performance of the camera claiming the world's fastest auto focus, the world's most auto focus points, and the world's fastest continuous shooting for a compact fixed-lens camera. Sony's claim of fastest auto focusing speed is that the camera can lock in focus in as little as .05 seconds. Sony increased the  number of focus points taken per shot to 315, and also improved continuous shooting performance enabling up to 150 continuous shots to be taken at the full 20.1 megapixels at 24 frames per second. This was updated with improvements such as an increased buffer and processor following the release of RX100 VI Cyber-shot DSC-RX100 VI. On June 5, 2018, Sony announced the RX100 VI. In this iteration, Sony introduced a new ZEISS Vario-Sonnar T* 24-200mm 2.8 – 4.5 lens zoom lens.
