I'm asking you this because last weekend I had a discussion with Reinhold Mueller on this very subject, and he answered unequivocally that the incompatibility of the 40mm Summicron with other M cameras was just a myth. I'm fond of the 40mm focal length (I've got an Olympus 40mm f2.8 in LTM and just got a Rollei 35 SE) and have been considering buying the 40mm Summicron for a M6.
