Nikkor 13mm f/5.6
The Nikkor 13mm 5.6 is an ultra-wide angle rectilinear lens which was manufactured by Nikon for use on Nikon F mount cameras until 1998. It has been dubbed 'The Holy Grail', for its low-distortion ultra-wide capabilities. The lens was produced by Nikon only upon receipt of an order, thus making it one of the Nikon lenses with the least number manufactured.
