Incredibly rare find! With original hood and CL-28 case.
Presented at the 1974 Photokina Exhibition the 18mm f/4 Nikkor has an angle of view of 100°, an aperture scale of f/4 to f/22, the closest focusing distance is 12″ (30cm) and comprises 13 elements in 9 groups. The filter thread is 86mm and will accept series IX (9) filters in combination with HN-15 lens hood. It weighs 315g. It combines an exceptionally wide picture angle with a relatively compact and lightweight body, thus effectively bridging the gap between the large ultra-wide-angle lenses and the more compact standard ultra-wide-angle lenses of 20mm and 24mm. In 1977 the lens was converted to AI and the first serial number was 190001. It ceased production in March 1982.
