The sharpness of this lens when it first came out 33 years ago is legendary compare to other products and is still sought after by classic Nikon aficionados and despite the digital revolution is still in production today like it was when it was introduced in 1977. The Nikon-Kogaku steel produce "Made in Japan" sturdy lens is quite heavy compare to the plastic made in China AF contemporary lenses (which actually yield a pretty fine pictures although not as emotionally satisfying). But for the fun loving photographer who likes to click the old-fashioned way it is most forgiving.
It's very satisfying that the digital revolution help us oldies produce instantly the same kind of pictures and manual technique that was fun 30 years ago. This lens with a couple of old sharp classic Leica, but we'll talk about this some other time, is now glued to my micro 4/3 and I probably will enjoy it for a long time to come.
