I don't know how the Nikon shifts are constructed, but if they're anything
like the Olympus ones, they use a friction pad to keep the lens in place. In
the Olympus lenses the friction pad is a simple velvet-like surface. If the
Nikon's do use grease, I would suspect one of the Nye damping greases would
be suitable. Be prepared for "sticker shock" though, they aren't cheap!
