The Reflex-Nikkor 1000mm F6.3 Nippon Kogaku, an extremely rare Nikon lens introduced in 1959. Originally designed for Nikon S series rangefinder cameras (mounted with required reflex housing), the 1000mm F6.3 lens was the first mirror lens made for the Nikon rangefinder cameras.
There were a few versions of this lens made (all versions of this lens are rare, with production numbers under 100 units). The final version was produced with a direct Nikon F mount (such as this one pictured). The lens takes 52mm filters that are located in a turret in the rear of the lens. On top of the lens barrel there are two handles as the lens weighs approximately 30 pounds itself and its carrying case adds another 10. This lens is no lightweight, literally or metaphorically speaking, 180 degrees from the handles rests a solid tripod mount which enables the user to turn the lens barrel 90 degrees. The lens focuses by way of bellows and its range is 98 ft. to infinity.
