what is a source for the xl1 viewfinder eyecup and the little rubber cup that protects the bottom of the iris wheel flange?
is there an online supplier for such things?
cheers,

I think you'll have to contact an Canon authorized service center or Canon directly. I mention the service center because they'll have the service manuals with the part numbers. The parts probably aren't too terribly expensive, but better do it now before Canon no longer has the parts and/or denies ever having made the thing.
