or a 12/5.6 at infinity.

I was surprised to find my shots with the Voigtlander 12  and Hexar RF of the
John Travalta film Swordfish weren't as sharp as my first 12 test shots on my
M6.   (the scene with the bus on its side in front of the bank was shot on
Main Street in Ventura CA).    I had the Hexar RF back focus checked, and it
was off.  It was fixed thru a friend at Konica Japan.    Since the factory
can fix the Hexar RF problem if it wants to, it completely escape me why some
claim there is no problem just because they have not personally encountered
it.    Bob Shell's  Hexar RF was also out of specs.  His was fixed by Ken
Ruth at Photography on Bald Mountain.     certainly not all Hexar RF's have
back focus problems, but some certainly do.   the only way to be sure is to
have a particular Hexar RF body checked by a good Leica tech.
