Re: [Leica] Focusing at infinity

My 135/4.5 Hektor is the same on both the IIIf and M4.  It does not seem to
focus quite to infinity.  The last batch I shot with this lens wide open
seemed a little soft. That may have been camera shake.  I confess I don't
shoot often with this lens because I have a hard time framing with either
the little corners in the M4 finder or my Tewe finder for the IIIf.
