Have had M4-P's, M6 and am now sticking with the MP. If I had the opportunity to buy a la carte, I would, because I'm a wide angle shooter, choose .58 and go with the M6 rewind. I know that will crush the clean, classic lines of the camera but I really don't like the knob post. and I've used the Leica rewind lever and hated it. Anyone have a CameraQuest one I can borrow and try, in BP, thanks
