Yessir, I'm aware of that, but thanks for mentioning it.

True, but my comment about the film/exposure was the fact that what I
saw on my monitor indicated a very short tolerance for rendering shades
of gray.
When I see that, I think of either the film type, some of which will
provide that, or processing, which if done outside the normal range of
temps and times can also cause that.

Quite possibly so.
MY contention was merely that it might be some thing other than an
indictment
of the lens quality.
Merely food for thought, Chris...
