I thought old 35mm film lenses on Canon were FD mount needing an adaptor and losing the AF?
And only Canon EOS lenses are sure to work, older third party ef lenses may thow up errors
28-80mm kit lens from Canon EOS 300 works brilliantly with my 5D2

Would a Canon EOS lens from a 35mm camera work on EOS DSLR?
And by work I mean autofocus....
I think it should .... Right?![]()
FD, pre-EOS, yes. But she specifically mentioned EOS lenses. And the FD lens was a purely manual focus mount, so there was no AF to lose.
