Eric,

We're talking about viewfinders here...

If you look through a Leica R viewfinder without a lens, and do the same
with a Nikon body, you'll see a difference.  And with 50mm lenses attached,
view the same scene with both cameras and tell me if they're the same.

Eric, are you telling me that if you took your 35 summilux and a 35 elmarit
into a dark room, that you could focus as well with both lenses?  With an
M, that's true. The image you see is through the rangefinder. But with the
R body, the max. aperature indeed makes a difference in ease of focussing.
You're using the light that goes through the lens.
