There are only a few of these: the 500mm f/4 P from 1988, the 1200 - 1700 mm f/5.6-8.0 P ED and the new 45mm f/2.8 P.here are a couple of ways to signify a D lens: Nikon usually marks its lenses as 50mm f/1.4D AF as opposed to 50mm f/1.4 AF-D, but it all means the same thing. Most AF-D lenses are AF and AI-s, and work great on manual focus cameras.
