This lens was one of the sharpest ones Nikon has ever made.
Btw, Minolta had the same optical lens with different coatings
with round aperture opening, which produced a better boké?!
(I have no idea who was an OEMer, but guess it was Nikon...)
was $1,600 @(forgot when)
Minolta AF 200mm F4 Macro APO G A-mount lens (it says APO)
