The D2x issue could be nothing more than a broken spring or jammed trip lever in the mirror actuation mechanism but it's way too delicate in there to meddle unless you know exactly what you are doing.
I have adjusted AF with screws, D200 I think but experience is called for with your problem, it would be very easy to make it unrepairable.
I`M Afraid that You`re Correct....
Funny thing about the 14-24....it seems to be at its " Sharpest " there where it Jams at 16mm focal length setting...curious that..
Anyone notice that with a Zoom...Any Zoom..??..
To me that would suggest a moving part is being pushed into it's correct position in a support slide at the tight point but the support is broken or displaced elsewhere along it's length, therefore not correctly aligned.
Does it rattle when the tight point is reached? If not that might confirm my theory. I might be inclined to leave it in the tight point, especially if you intend to post it...
Some lenses are incredibly frail in their construction, using all sorts of ways to squeeze the complex mechanism into a tiny space. The 25-50 I had was very sharp but suffered a drop while on my D1, the D1 was fine of course!
I opened up the lens and the innards slid on three small rods which were held in position with sticky tape. The impact from being dropped, had torn two of the rods from their flimsy supports. That exhibited the same 'slack' and 'tight' feel when zooming and focusing. I liked that lens, it was small and very sharp, with good contrast but although it did improve it's behaviour, I got rid during one of my equipment culls.
