I shoot a few rolls of B&W with an M6 at nearly all of my weddings, I'd love to shoot a whole wedding with them but the AF and high iso of modern DSLRs is very hard to resist, certainly getting my film back is so much nicer than loading files on to the computer, perhaps because most of the digital I'll have seen on the back of the camera already so no surprises, but I honestly believe I get a different result from using the M6, beyond the film digital thing, although it may just be contrast of the lenses, but I wouldn't like to have to decided one or the other.
