The Nikkor AF 20mm f/2.8 D is a full frame ultra wide-angle lens released back in 1994. There were several design updates of most ultra-wide zooms during the last years but for whatever reason most manufacturers didn't really care for their wide-angle fix-focals recently. On APSC DSLR, the field-of-view of the lens is equivalent to 32mm so it's more a moderate wide-angle within the APS-C DSLR scope.
