Well, yes, sort of. JRP's comment is correct but incomplete. A fisheye becomes a non-rectilinear corrected wide angle lens. With your rectilinear wide angle lenses, you can essentially just consider the lens to be multiplied by 1.5x so a 14mm lens would have the same field of view as a 21mm lens would on a 35mm camera. Note that the perspective doesn't change from that of a 14mm lens, just the field of view. This is farely noticable with the wide angle lenses. With the fisheyes this especially holds true. So in essense, yes a 16mm fisheye becomes a 24mm fisheye with a totally different look from a 24mm lens. I've attached the crop from the bottom edge of a photo taken with the 16mm Nikor on the D100. Notice how the straight edge of the bar counter is heavily curved, looking almost circular.
