It is the successor of the Canon EOS 350D, and upgrades to a 10.1 megapixel CMOS sensor, a larger continuous shooting buffer, an integrated image sensor vibrating cleaning system (first used in a Canon EOS DSLR), a more precise nine-point auto focus system from the EOS 30D, improved grip, and a bigger 2.5-inch (64 mm) LCD with 230,000 pixels and a larger viewing angle which replaces the top status screen.

The 400D uses the DIGIC II image processor. The 400D file numbering system holds 9,999 pictures in one folder. Support for the Media Transfer Protocol (MTP) USB protocol is available since version 1.1.0.
