This short video from the good folks at the U.K. boutique Nikon store Grays of Westminster shot last year shows one of the most famous Nikon lenses of all times – the Fisheye-Nikkor 6mm f/2.8. Introduced back in 1972 (later Ai-S versions came in 1983) only a very small number of this super size super wide angle fish-eye lens were ever produced.
This 5.2KG behemoth has a whooping 220 degree angle of view (compared to your average 180 degrees most fish-eye lenses has). Its made out of 12 elements and if you are lucky enough to find one online you would have to pay anywhere from $80k-$160k (you can find a little bit more on the history of this lens on mir).
Below you can see an unboxing of this very special lens
