ok, I know you did'nt ask, but there is an adapter that will allow you to mount manual focus (Contax/Zeiss) lenses on EOS bodies. If you want something really distinctive, check into that one... I did a google search on this a few months back and pulled up some interesting finds.
Obviously you will loose, AF and some of the bells and whistles, but you will have something that virtually no other canon shooter has, razor sharp, contrasty and beautiful colors. (not that canon isn't already razor sharp, contrasty and beautiful colors...)
Here's a site with mabey some info: web page
