Canon 1100D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Canon 400D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the 1100D and 400D sensor size comparison.
Canon 1100D and Canon 400D 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 400D has 20% larger pixel area (32.60µm2 vs 27.00µm2) compared to Canon 1100D, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
DxOMark Sensor Scores
At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.
