    My OM 50mm f1.8, on a GH1, focuses past infinity, ie with the ring turned all the way to stop, where the infinity symbol is exactly aligned with the focus mark, it's past infinity. I recall it did the same thing on my OM2s SLR that the lens originally came with, so it's the lens itself, not the adapter or the camera. I also seem to recall reading something long ago (camera was bought mid-80's) to the effect that this was "normal" for this lens. So, anyone else with this lens notice the same thing?

    yes, depending on the climate - is it freezing cold or heat the focus can shift slightly - my OM 50/1.8 focuses just past infinity - maybe 1-2mm extra, they are made that way just in case -
