Description

This used to be my workhorse for medium tele-photo and landscape, tack-sharp to a fault and built like a tank as used to be for old Nikon manual lens production of the 70's. Tested here in DX format (APS-C) at its maximum aperture of f/2.5. Overall pleased with the correction and surprised that it didn't throw out a lot of LCA. There is some unfocused violet giving a faint purplish cast to some of the field stars. Brighter stars show some contained coma but that doesn't grow out of proportion as the field angle increases. A potential worthwhile addition to everyone's arsenal of star-capable lenses and quite cheap too.
