It is a great lens but was designed for the Leitz/Minolta CL. The CL lenses have a different, steeper lens focusing cam than normal M and CLE lenses. The CL camera, which does not have to focus f1.0 lenses, has a simpler, shorter based rangefinder mechanism. The M cameras' rangefinder is fine tuned by adjusting the length of the roller arm which means that it can be in a slightly different position horizontally from one camera to another. The short ending to the long story is that quite often the M and CLE camera's rangefinder will not couple to a CL lens correctly. Point the combination at a point at least two miles away and, if everything lines up OK at infinity, it should be fine. If it does couple correctly, bear in mind that it may not work with your next/other body(ies). - ------------------------------------------------------------------------ > From: Rolf Katzenstein <rgk@farmington.com> > > Will the 40mm f2 Summicron couple to an M6 rangefinder properly?
