Ebay Watch: Leica Prototypes, 2000mm Lenses, Photo Booths and More
Nikon 11/2000mm Reflex Nikkor C Lens- $20,700 or Best Offer This massive “beer barrel” of a lens first made its debut at the Photokina tradeshow in Germany back in 1970. According to Ebay seller SHPhoto-gmbh, Nikon only ever manufactured a few of them.
The lens contains a series of mirrors, two in the back and one in the front, that are used to bounce light around, effectively maximizing the lens’ focal length, without adding to its physical length. The result is an extremely stocky lens.
Just incase you are wondering, the minimum focusing distant of this lens is 20 meters away. It also weighs 55 pounds.
