this is a pretty stupid thread, but i'm honestly trying to do this. admin - move if necessary. think if i talked to canon, they'd send a model they could not profit from? ie - a diamond-cut scratch across the rear element? other than canon directly, who would be a good bet to get a decent piece of useless glass? doesn't HAVE to be a 50 1.2 (i realize it's new, and not very many have had the chance to get abused yet) anything from any manufacturer would work as long as it's not a big tele.. it could even be nikon but i'd prefer not to ash where i eat. i want to make an ashtray.
