Perhaps even when Leica doesn't emphasize resolution, the resulting lens
ends up resolving better than most. Actually, I'd rather have a lens
designed for greater contrast. Much better image characteristics, IMHO. 

In the lens design book that Canon put out a few years back they gave
examples of images  from lenses with high res/low contrast versus high
contrast/low res. The latter won hands down. It wasn't even a contest. Micro
contrast has more impact than resolution on perceived "sharpness". I'm no
expert on optics, but I know when I see something I like.

I once read that the 35/2-R was designed with emphasis on contrast over
resolution. I don't know if that's the case, but it sounded interesting. I
have a late 35/2-R and it's a great lens. It's fantastic paired with
Kodachrome -- or any b/w film.

If that's true I'd be curious to see what an emphasis on resolution would
have produced.  As it is the resolution is great, and the contrast,
especially the lack of veiling flare, is exceptional.  A former LUGger
mentioned some flare in odd circumstances, like when the sun was in certain
places outside the field of view but I suspect that was from reflections
inside the camera's mirror chamber.
