It has a superior Stacked CMOS sensor with excellent image quality that surpasses all the previous generation RX100 cameras, faster Bionz X processor with a front-end LSI capable of handling up to 24 fps shooting speed, 315 phase-detection autofocus points, 4K video recording at up to 30 fps and very respectable slow motion video recording capability up to 960 fps. It can handle shutter speeds of up to 1/32000 sec, has a very nice 2.36M electronic viewfinder (EVF), incredibly fast autofocus and a few other nice extras, such as anti distortion shutter and ability to set minimum shutter speed when shooting with Auto ISO enabled.
