Hello all:
I just purchased a 50 mm f2.0 Summitar in Leica screw mount and will be using it on my Ms with a LTM to M adaptor ring. I just did that. The strange thing is that when I mounted the combo on an M (in fact, a CL, as it was just within immediate reach of my hand), the focus reference mark on the lens mount is about 20 degrees to the left of the vertical position (looking from above), while the aperture reference dot is at 0 degrees (right on top). Strange!
Oh, the LTM to M adaptor ring is a genuine Leitz Wetzlar 50 mm ring.
Any ideas?
Thank you in advance.
Guy
