All of Nikon's AF lenses have some sort of manual focus ring, although on some of them it's almost vestigial. The missing ring on the G lenses is the aperture ring. Therefore, the G lenses will not meter with the Photomic finders, and if mounted, will always expose at the same aperture setting. You could use a G lens but it would be very limiting.
