The Sony DSC RX-100 Featuring: 20.2 megapixels, large 1″ Exmor™ CMOS sensor, F1.8 Carl Zeiss Vario-Sonnar T* lens with control ring, 3.6x zoom, P/A/S/M modes, JPEG and RAW image capture, Full HD 1080/60p video with manual control and a whole bunch of interesting features.
My impression of this camera is that it is a lot more advanced than other compact cameras, and the fact that you can use full manual together with its awesome (for a compact camera) lens. It has a panorama mode, image to vector conversion and is one of the few compact digital cameras with RAW.
Compared to the average point and shoot sensor size, the RX100 has a very large, 1″ CMOS sensor. It is a sony EXMOR sensor to be able to capture more light in your pictures and reproduce every detail even in low light conditions. It takes pictures at 350dpi, which is higher than most cameras do. The sensor is probably better than most DSLR sensors.
