This fisheye lens from Nikkor was first introduced in 1970 at the Photokina trade show in Cologne and was the first “extreme wide-angle” lens ever available. The lens went into production in 1972 and was only available on special order. It covers a 24 x 36mm image area with a massive glass dome which dwarfs the camera attached. It was mostly used for commercial applications but many die-hard amateur photographers have drooled over it for 40 years. The lens, which uses 12 glass elements and weighs 5.2kg, is now available from Grays of Westminster if you can afford the $161,400.00 price tag.
