I have several Nikon lenses that I have purchased over the years for my Nikon film SLR (28-85mm f/3.5-4.5, 80-200mm f/2.8, 50mm f/1.4, 85mm f/1.8) and a Tokina AT-X Pro 28-80mm f/2.8. After reading that these lenses would work with the D80, I purchased the body only, attached the Tokina and EVERY single photo was out-of-focus even though the autofocus was on and the shot looked in focus in the viewfinder and screen on review. The other lenses hunt around so much I miss most of the people shots I'm trying to capture (Christmas morning-argh). I knew some of the functions wouldn't work but not autofocus.
Any comments on why this is happening? My husband is freaking out because now I want a DX lens!

Sorry to hear about your problems
There is no reason why a DX lens would be better at AF than the lenses you have, except that it would be a bit faster since it would have an in-lens AF motor. I suspect that the problem lies elsewhere. What AF settings are you using on the camera?
You might want to have a look at this article on the CAM1000 AF system. It was intended for the D200 but quite a bit of it can be applied to the D80.

A DX lens won't make any difference to the focus; all it does is throw a smaller circle of llight than a 'normal' (FF) lens.
1) Are the problems only seem to be with the Tokina? If so maybe just trade it in for an equivalent Nikkor - that may fix it.
2) When you mention 'screen on review', are you zooming in to be sure? The full view is no indication of accurate focus or exposure, as I learned the hard way cutting my teeth on the D70!
