I have both versions of this lens. I used the “D” model to shoot 33,000 rock n’ roll concert posters on a vacuum board that I built myself, and it did a great job.
I prefer not to have G” lenses, but still have a few. I like both versions of the 60mm Macro-Nikkor, but have a sense that the old “D” has something the newer one does not, but I can’t prove it myself. I use neither of them much, except on an old Polaroid copy stand, where they are great, but they are not highly corrected enough for my regular nature work.
