What is the sensor size of the Canon 20D?
The Canon EOS 20D is a digital camera that has an APS-C sensor at its core. This imager measures 22.5mm in width and 15.0mm in height, so that the total imaging area of the sensor amounts to 338 mm2.
The 20D provides an image resolution of 8.2 megapixels, based on 3 504 horizontal pixels and 2 336 vertical pixels.
Sensor size comparison with a film slide
The sensor diagonal measures 27mm, which gives rise to a format factor (or crop factor) of 1.6. Hence, the Canon 20D 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 20D 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.
