Most people won’t be surprised to learn the Canon Digital Rebel XTi / EOS 400D now features a larger 2.5in screen and Canon’s Picture Styles, but following the earlier Canon EOS-30D, many equally expected the new entry-level body to employ the same sensor as its predecessor.
In addition the EOS 400D / Rebel XTi is the first Canon digital SLR to feature a self-cleaning sensor which shakes off dust particles. Reference frames can also be tagged to images for automatic removal of more stubborn dust particles later using supplied software.
