The 400D (Rebel XTi in North America) was Canon's 2006 entry-level DSLR: the 10.1MP resolution was a notable upgrade over the 350D's 8MP. The pre-video era design reflects the period when consumer DSLRs were stills-only — video on DSLRs arrived with the 5D Mark II in 2008. Accepts all Canon EF and EF-S lenses.
On the used market the Canon EOS 400D is very affordable as a vintage entry DSLR. Condition checks: sensor for dust, shutter actuations, NB-2LH battery health. No video. Compatible with Canon EF and EF-S mount lenses.
