Originally posted by RICHARD L. The only one I found subpar on the 67 II was the 90 mm f/2.8 and it may still surprise me.
It's not quite on a par with the 645 90mm f2.8 DFA, but I have used it on the 645Z (in some cases before I owned the newer lens, and in one recent case merely because the older lens is lighter and smaller, so it was easier to carry with me on a hike).
Here are a couple of the results. Personally, I think it does very well! (FYI, this is a very late 67 90mm lens; I also have the 6x7 90mm LS lens, which optically I don't like as much). The star trail image even involved using the lens close to wide open (for the sky area anyway)...
