Canon 400D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Canon 1100D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the 400D and 1100D sensor size comparison.
Canon 400D and Canon 1100D 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 compared to Canon 1100D, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
