This lens has a plastic/composite mount. It doesn't short *any* of the contacts on the D's lens mount. The D doesn't even know it has a lens mounted! This appears to be normal behavior when there is no lens. (I verified this by taping over the contacts on an FA lens, same result.) Oh well, maybe this will save somebody else some confusion in the future. ;-) And, I just missed the garbage truck *again* playing with this silly thing! :-(
