In most cameras, a new sensor means more megapixels, and maybe some extra low-light prowess. If you're lucky. The new sensor in the Sony RX100 IV Camera offers far more than that. The latest update to the powerful point-and-shoot centers around a stacked Exmor RS CMOS sensor, with both advanced signal processing and an attached DRAM chip. These latter two features enable new capabilities like slow-motion video capture at up to 960 fps, an Anti-Distortion Shutter with a maximum speed of 1/32,000 of a second, 4K recording, and burst shooting of up to 16 fps at 20.1 megapixels, all in the same pocketable body and with the same sharp Zeiss lens.
