So here's something I've been wondering about. Are there any combinations that won't physically fit? I happened to be sitting next to a guy this weekend who had a 5dm2 and either a 50 1.2l or an 85 1.2l. The lens was huge and it looked like there was no way that it could fit on my little t1i. Is it possible?
They all fit on every body. Sometimes only by a hair, but it fits.
