Nikon has not gone all the way with the MF compatibility, however, because you cannot use exposure modes other than "A" or "M" with them, but matrix metering will work. Since setting the actual aperture of any Nikkor can be done from the camera, as long as the camera identifies the lens in use, I was in the beginning a little surprised that "P" or "S" modes wouldn't work (not that I would fall into the trap of using these "exposure for dummies"-modes, of course). Neither is it possible to set apertures for non-CPU MF lenses by the command dial (if the MF lens gets a CPU implanted in it, however, you can use the dials although Nikon won't acknowledge this possibility). My analysis is that Nikon could easily implement these features if they wanted, but refrained from doing so as not to run into trouble with inaccurate exposure if an AI'd or AI lens was used. These older lenses have a non-linear response to stopping down the aperture, and you should always set the aperture directly on the lens, not with the camera's controls. Saved by the bell as it were, Nikon to the user's rescue.
