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 at: www.David-Ruether-Photography.com/articles.html).
