There are many more camera bodies where the AF 80-400mm lens is 100% compatible then those that are not.
Nikon used two different types of auto focus motors, one built into the camera body that drives the auto focus mechanism in the older AF lenses and the newer AF-S lenses where the AF motor is in the lens and receives auto focus info from the body to the lens via the body/lens contacts.
The D200 can autofocus both the old and the new types of auto focus lenses. Nikon has eliminated the AF motor in the body of the newer D3000, D5000, D40 and D60 series of bodies. The AF 80-400mm must have the old AF motor in the camera body in order to autofocus. However the AF 80-400mm lens is compatible with all of Nikon DSLR bodies with the exception of auto focus. You can still manual focus the lens. If you want the AF 80-400mm lens to autofocus you should have the D7000 and not the D5100 body.
