[Leica] R glass on Nikon question - hopefully the last

[leicar at q.com (Aram Langhans)]

Exactly, Jim.  That is the way I expected it to work since that is the way 
it works on my Canon, with the slight metering problem Canon's have with 
stopping down.  There must be something the clerk did not know.
