What is the sensor size of the Sony RX100?

The Sony Cyber-shot DSC-RX100 is a digital camera that has an one-inch sensor at its core. This imager measures 13.2mm in width and 8.8mm in height, so that the total imaging area of the sensor amounts to 116 mm².

The RX100 provides an image resolution of 20 megapixels, based on 5 472 horizontal pixels and 3 648 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 15.9mm, which gives rise to a format factor (or crop factor) of 2.7. Hence, the Sony RX100 is a crop-sensor camera, as its sensor is smaller than a traditional 35mm film slide or negative.

Sensor specs and performance

The table below compares the sensor specs of the Sony RX100 to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
