I have a friend who adapted his black 65 mm Elmars to a Nikon tilt/ shift bellows. Apparently the image circle is not that big and you can't shift or tilt very much at all. He also had a hell of a time with paint flecks from the diaphragm blades and has learned to quickly field strip and clean the lens.
