I presume you have the manual focus Nikkor? I have one myself; it does a nice job especially on a D850. I shot the "Dragon Lights" lantern festival in downtown Chicago last year; used that lens exclusively on a D850. From my experience the older Nikkor manual focus lenses perform better on a D850 than on my D7100; I have tested them all on both bodies. Lenses are leftovers from my film days, and glad I did not get rid of them.
Yes, mine was made long before autofocus. These old lenses are so solid and sharp!
