What is the crop factor of the Canon Rebel?

The Canon EOS Digital Rebel is equipped with an APS-C sensor, whose diagonal measures 27.3mm. The sensor has a crop factor (or format factor, or focal length multiplier) of 1.6.

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 1.6, the sensor in the Canon Rebel is smaller than the receptor area of a 35mm film slide or negative. As a result, a lens that is attached to the Canon Rebel 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 31mm lens on the Canon Rebel will provide the same angle of view and depth of field as a 50mm normal lens on a film camera (31mm * 1.6 = 50mm).

Sensor specs and performance

The table below compares the sensor specs of the Canon Rebel 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.
