Hi Steve,
I'm glad you asked about the DR.  What you have is a very high
resolution lens with relatively low contrast.  You ask what that means:
your negatives will have a tremendous amount of detail but the
differences in tonality will be relatively minor compared to a modern
lens formulation.  Well, what does that mean to the bottom line image?
To be really blunt, PS makes this lens sing, a little USM and some curve
adjustments and you have a wonderful image.

Two things to note about the DR, compared to modern lenses it is prone
to veiling flare and second, even a clean one needs to be CLA'd for best
results as even the newest are something like 35 years old.  Also, pick
the person who does the CLA very carefully as there are some air lenses
that need to be spaced to spec or the lens performs poorly.

This first link was taken in very late evening light just behind the NYC
library.

My second image demonstrates that the lens handles color just fine.

I must admit however that I don't have an image up that really
demonstrates what this lens can do.

a venerable  old Leitz Wetzlar lens, I know... thought by many to be 
their personal favorite, of all... I wonder if those...who have been 
there/ done that could comment on the properties of this lens, its 
capabilities, and where they would find it most useful....

I have seen some images with it that impress, with their resolution 
and fine detail...thanks, Steve
