I
agree, hence my specification, "all *good* *well-aligned* lenses for 35mm
perform
about the same"...;-)
The
differences among the above from f8-f22 are minimal, if discernable at all,
though
the exceptional lens that performs a bit above the others is possible,
and the
17-35mm Nikkor is excellent (reviewed and compared with other
Nikkors
