Nikon Mount Fish Eye Lens f.8 12mm Accura: This spotless Nikon mount, Fish Eye is in beautiful shape, free of scratches, scrapes, dust, fog, haze and fungus. The aperture's internal Waterhouse click stops are f/8, f/11, f/16, and they move smoothly. As with most fish-eye lenses, the front element has a significant bulge. A metal lens shade/cap with cover protects that nice piece of glass. This fun lens also has a rear lens cap and a soft padded pull-string case.
