понеже явно не си отворил линка, който ти пуснах…
Right after I bought the lens and noticed this, I sent it to Nikon to have them check it out. This is the response I rec'd:
"Due to improvements in auto-focus technology, you may find shooting situations where an older lens, any lens previous to our AF-S technology, does not appear consistently sharp. This is the result of technology growth with the auto-focus system. The lens in question is less consistent in certain situations when used with one of our current DSLR cameras but measured over all possible shooting situations, this lens remains excellent. Many improvements have occurred, even over the last few years. Again, it remains excellent for most situations.
There are no adjustments we may make for the specific situation you requested and we hope our explanation helps. If you have any further questions, please let us know.
Thanks for using Nikon products!

On page 367 of the D3S user manual, it says:
"When focusing at minimum focus distance with AF 80–200mm f/2.8 […] lens at maximum zoom, in-focus indicator may be displayed when image on matte screen in viewfinder is not in focus. Adjust focus manually until image in viewfinder is in focus."
Most other cameras since 2004 have a similar warning about this lens in the user manual.
There are 3 last century lenses that do not focus correctly at minimum focus with AF - as explained in camera instructions. If you have one (last made in 1998) you use manual focus for minimum focus work
As Nikon explain, if you have one of these 4 old lenses and want to shoot at maximum zoom minimum focus the only way to get sharp images is manual focus.
