What is the crop factor of the Sony RX0 II?

The Sony Cyber-shot DSC-RX0II is equipped with an one-inch sensor, whose diagonal measures 15.9mm. The sensor has a crop factor (or format factor, or focal length multiplier) of 2.7.

The crop factor is defined as the ratio of the 35mm full-frame film diagonal to the diagonal of a digital sensor. This number indicates how a lens behaves in relation to the size of the image sensor.

Sensor size comparison with a film slide

With a crop factor of 2.7, the sensor in the Sony RX0 II is smaller than the receptor area of a 35mm film slide or negative. As a result, the lens that is attached to the Sony RX0 II will offer a narrower angle of view and provide deeper depth of field than a lens of similar focal length and aperture on a film camera. The equivalent focal length is obtained by multiplying the actual focal length of the lens with the crop factor. For example, a 19mm lens on the Sony RX0 II will provide the same angle of view and depth of field as a 50mm normal lens on a film camera (19mm * 2.7 = 50mm).

Sensor specs and performance

The table below compares the sensor specs of the Sony RX0 II 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.
