My mom has an old Canon SLR film camera, and it might make my D70 vs 350D easier if I can use her lenses. I finally have the lenses in my hand and I'm trying to figure out if they'll fit. Here's the first one (not mine, but this is it): http://cgi.ebay.com/CANON-FD-135mm-...ryZ48552QQssPageNameZWDVWQQrdZ1QQcmdZViewItem The other one I can't find online, but this is what it says on the outside: Samigon Coated Optics 1:2.8 f=28mm KX.410487 I have no idea what 90% of that means, haha, but I figure some of you will. So will these fit the Rebel XT? And even if they do, are they good enough to sway my decision between those two? Thanks.
