Canon 10D has a
6.0MP APS-C (22.7 x 15.1 mm ) sized CMOS sensor . On the other hand, Canon 30D has a
8.0MP APS-C (22.5 x 15 mm ) sized CMOS sensor .
Below you can see the 10D and 30D sensor size comparison.
Canon 10D and Canon 30D have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Canon 10D and Canon 30D sensors have been tested by DxO and the results show that 30D has a better overall score of 59, 2 points higher compared to 10D's score of 57.
