Konica Hexar RF and Leitz lenses in Leica and Rangefinders Posted January 1, 2001 Re your second question, the phenomenon you described indeed happens to M-mount leicas, used with screw mount adaptors. I use an M3 and most of my lenses are either Leica or Canon screw mount lenses. The discrepancies occur with the shorter lenses, but not with lenses above 50 mm. I did have some problems with the 85mm 1.9 canon on the M3, but the focussing errors were not too great. I suppose that focussing errors are tolerable with the shorter lenses. With Konica Hexars, the same could probably apply as well.
