The Nikon Nikkor 6mm f/2.8 – a lens first produced in 1970 for the Photokina trade show in Cologne, Germany – was, at the time, crowned the “world’s most extreme angle lens” with the ability to shoot 220º on a 24x36mm. When it became available to the general public in 1972, it was still only available to special order – so anyone looking to drop £100,000 on some new photography equipment will be glad to know that Gray’s of Westminster have spent six months tracking down one of the lenses from overseas. In mint condition, the lens uses 12 glass elements in nine groups and weighs 5.2kg. It has a minimum focussing distance of 25cm, features a slip-on front lens cap and is delivered in a rugged metal case. (via HUH)
