I had this with my D300 back in the day.
Had it for a good year(minimum), and at the time was happy enough, but just something not 100% right.
Overall IQ, colour, bokeh, etc ... was superlative! In that respect one of my favourite lenses.
But at 200mm and f/4 or less, not the sharpest lens, made worse with misfocus issues.
Test the then new Tamron 70-200/2.8(non VC, very first edition) .. so much better sharpness, and 99.9% as good in other measures of IQ by comparison.
More importantly it allowed easier refocus as required, where the 80-200 required the A-M ring to be moved first, then focus adjusted as needed. Too clunky, and then from reading of it, this A-M focus locking ring was all too fragile to be using with regularity.
Unsealed front lens element meant dust inside lens within a day of using it!
I hate UV/protective filters, but this lens required it to make it sealed in some sense.
Loved the lens, hated it's vices ... Tamron had a better alternative at the time.
BUT! ... if you ever needed a hammer on a spur of the moment situation .. the 80-200 AF-D lens would provide for 'ya!
If you really want a lens of this focal range, I'd strongly argue that the Tamron is better most of the time.
If you want smoother bokeh than the already smooth Tamron can provide and for a decent price range .. then the 80-200 AF-D could be better, considering it'd also make a good emergency carpenters' tool too.
