Jag blev ju nyfiken!

Minns då jag tittade på en zoomlins till min Pentax nån gång i mitten av 1970.talet. En billig, begagnad piratoptik. Jag trodde knappt mina ögon då jag kollade i sökaren. Jättekrokiga linjer ena änden, kass i mitten, sen skruvade jag bort objektivet och tackade för mig.

Ett sökresultat för första versionen av ditt objektiv:

Without a doubt the worst lens I've tried so far, at least on the FX format. The performance of this classic Nikkor lens is so bad it's almost indescribable. It's like you have to try it to see how bad the lens is.
In the center images can be "sharp" using an aperture of f/5.6 to f/11 at focal lengths between 50 and 70mm where the lens performs its best. On the wide side of the lens it never gets sharp in the corners even when shooting a flat field, regardless of aperture. Same goes when using the lens on 86mm.
Later versions of this lens are supposedly better when it comes to performance, but the zoom range is not great, and quite honest it's quite awkward. I don't see any reason for getting this lens unless you want a paper weight, or if you just want to own a classic lens that is classically bad, or if you want a something to compare the word useless for?
