A lens that can see behind itself? That’s an interesting proposition. This 220-degree viewing angle fisheye Nikkor lens was presented by Nikon at Photokina in 1970. Despite its amazing fisheye capabilities the lens is still fast at f/2.8, a property that’s due to its massive construction, with 12 elements in 9 groups that will dwarf any camera attached to it.
We’re sure the engineers that created this mammoth lens had a great time watching people being awed by this monster lens. The 6mm f/2.8 fisheye measures 24cm in diameter and 17cm long, weighing 5.2Kg (11.5 pounds). Its production started in 1972 and was only made available as a special order for scientific, industrial and special effects applications for shooting portraits and architecture.
