Canon 1000D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Canon 450D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the 1000D and 450D sensor size comparison.
Canon 1000D and Canon 450D have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 1000D has 20% larger pixel area compared to Canon 450D, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Canon 1000D and Canon 450D sensors have been tested by DxoMark. DxoMark 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. Of the two cameras that we are comparing, 1000D has scored 62, 1 points higher than 450D.
