Greg:

Thank you, good point. Although I have found rangefinder focusing to 
be less than reliable for subjects at the edges of the frame wide 
open. After you focus and recompose, it is difficult to assure that 
you are keeping the subject in the exact plane of focus. Perhaps I 
have a good sample, but my 35 summicron is quite sharp off center at 
f2, but often, I find that I have missed the focus by a bit. Still, I 
don't think I've ever made a composition with the subject skirting 
the edge of the frame, so I've never encountered this problem.
