What is the sensor size of the Canon XSi?

The Canon EOS Rebel XSi is a digital camera that has an APS-C sensor at its core. This imager measures 22.2mm in width and 14.8mm in height, so that the total imaging area of the sensor amounts to 329 mm².

The XSi provides an image resolution of 12.2 megapixels, based on 4 272 horizontal pixels and 2 848 vertical pixels.

Sensor size comparison with a film slide

The sensor diagonal measures 26.7mm, which gives rise to a format factor (or crop factor) of 1.6. Hence, the Canon XSi 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 Canon XSi 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.
