The rare Fisheye-Nikkor 6mm f/2.8 has caused an internet sensation since its discovery was first reported by Amateur Photographer on Monday.
‘There has been an extraordinary amount of interest... The response has been incredible and keeps on going,' said Gray Levett, co-founder of Grays of Westminster, the London store which sourced the lens overseas a few weeks ago.
Speaking today, Levett revealed that the photographic gem has been sold to an unnamed ‘private collector' for the full £100,000 asking price.
Credited as the world's most extreme wideangle lens to cover the 24x36mm image area, the Fisheye-Nikkor 6mm f/2.8 was unveiled at the Photokina trade show in Cologne, Germany in 1970.
It is believed to be one of only a few hundred ever made.
