The DRAM memory chip will definitely increase the processing speed of the camera and its CMOS’ design will allow more space for the light sensitive portion of each pixels by dividing the photosensitive region of the sensor in different layers.
The recently announced Sony RX100 IV compact camera has the similar specification compare to its predecessor Sony RX100 III including the similar focal length range of 24-70mm, and have maximum aperture of f/1.8-2.8 which is beneficial for working in low lighting and controlling focus throughout the zoom range.
The Burst rate is increased by 16ps as compared to its predecessor’s 10fps and hence its shutter speeds up to 1/32,000 sec comparatively more than its predecessor’s 1/2000.
The one of the magnificent features of the RX100 IV is its capability to capture and record 4K video, in camera, using the XAVC S codec with full pixel readout.
The Video record time for shooting 4K is 5 minutes but the RX100 IV can record video up to 40x super slow motion video at 960fps, 480fps and 240fps.
Sony has the pop-up SVGA OLED electronic viewfinder. It has 2.35 million dots, compared to 1.44M dots on SVGA OLED Tru-Finder of the RX100 III.
