[Leica] R 250 Telyt for my Nikon D700

[leicar at q.com (Aram Langhans)]

Wayne.  I think Howard said just about everything about your decision.  I 
would just like to add one thing.

When I made my choice (Canon) there was only one possibility.  Now, I think 
it comes down to one question.

Do you want to still use your R lenses on an R body any time soon?  If so, 
the Canon would be the best choice, over Olympus unless you would like the 
2x crop factor.

If you don't want to use them concurrently on an R body then Nikon is the 
choice for it solves all the Canon exposure problems.  If and when Leica 
announces their solution, you can always reverse the process and use them on 
the "New R".....

My 2 cents.
