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

[jhnichols at lighttube.net (Jim Nichols)]

Hi Aram,

I am awaiting responses to your questions, because this all seems like the 
result of too much information.  I use Leica-R lenses on Olympus 4/3 
cameras, and the process is very simple.  I set the selector to "A", and the 
camera determines the light quantity at any f-stop I select.  It then sets 
the appropriate shutter speed for the ISO I chose, and the light available 
from the lens.
