“No Lens Attached”

The D60 has a message it likes to show sometimes at varying points in its operation with a manual lens attached. Whether attached to the Orion telescope or the 500mm lens, the camera will state “no  lens attached”, even though the manual states that the camera accepts manual (non-CPU) lenses. There is no way to tell the camera about the lens that is attached to it either, which is another annoying factor, since it means I must manually enter my lens information into ExIF as an afterthought.
