A problem with manual focus lenses on digital bodies is that most digital cameras don’t have a focus screen designed for them. You can set them up that way but it’s expensive. The camera may not be able to couple with the aperture, that means you have to do that manually as well.
Almost all of the Nikon F series is compatible with all the DX series cameras. They don’t work with the D40 and the like, but not otherwise a problem. Nikon has done a great job of maintaining compatibility.
Afraid of that...........
