What is the crop factor of the Canon G5 X?

The Canon PowerShot G5 X 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 Canon G5 X is smaller than the receptor area of a 35mm film slide or negative. As a result, the lens that is attached to the Canon G5 X 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 Canon G5 X 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 Canon G5 X 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.
