RARE – COLLECTOR’S GRADE! COMES COMPLETE WITH DOME SHAPED FRONT CAP, NIPPON KOGAKU REAR CAP AND SPECIAL FINDER!
Together with the 6mm f/2.8 lens, this is the widest of the Fisheye-Nikkor lenses, with an angle of view of 220°. With its 6mm focal length and extremely wide coverage, subjects slightly behind the camera will also be included in the image. There are six filters built in on a rotating turret: L1A (Skylight), Y48 & Y52 (light and medium yellow), R60 (Red), XO (green) and O57 (orange). The aperture range is: f/5.6 to f/22, Elements/groups: 9/6. Diaphragm: Manual. Compact and lightweight – only 430 grams. Separate 160° Fisheye Viewfinder (DF-1) for bright viewing. The lens cannot be used with Nikon cameras that do not have a provision for locking the mirror in the “up” position. This lens was only available by special order. Apparently, the 6mm Fisheye-Nikkor was originally produced as a survey lens for the National Arctic Survey to take pictures of the whole sky and cloud formations unhindered. First production: January 1969. Our research suggests that serial numbers began with 656001(excluding five prototypes) and apparently LESS THAN 100 WERE PRODUCED MAKING THIS ONE OF THE RAREST LENSES MADE BY NIKON!
