Since you still have the F3 you can tell if your lenses are AI compatible or not. The F3 can use both AI and non-AI lenses by putting the AI meter coupling lever located at the 1 o'clock position around the camera lens mount up or down. If your lenses contact and move the lever when it's in the down position the lens is AI. If the lens mount interferes with the lever so it has to be moved out of the way by pushing the little button next to the lever, it is non-AI and should not be used on the D7000.
