Hi all

I'd like to get into back to basics photography, and am doing the rounds on ebay looking for a Olympus OM film SLR. Part of the attraction is I can get some nice prime lens with these cameras, which I think can also be used on the 5D2 with an adaptor.

However, I've been reading up on it and it seems the 5D2 has a larger mirror than other EOS DSLRs and sometimes the mirror can hit the lens, according to cameraquest.com

Does anyone have experience in using an old OM lens on a 5D2? if so have you encountered any problems?

Also, can anyone explain how the aperture priority would work with a manual lens?

Cheers.
