The first reflex Nikkor was not designed for the SLRs. The gigantical Reflex Nikkor 2000mm f11 - the longest commercial production focal length of Mirror lens for 35mm SLR photography. It was first introduced in 1972, where at the same time, the widest angles among all - the Fisheye Nikkor 6mm f2.8 was introduced at the same year. The 1000mm Mirror lens here present some photographic objectives. It may not be a everyday lens, but just like any Reflex lenses, it possess some optical characteristic on its own.
Dramatic images are possible in sports, wildlife, travel and astrophotography.
Very compact and light for its long focal length. Telescopic lens hood. We are so used to the 500mm f8, 1000mm f11 'standard' aperture formula. Reflex lens for their 35mm rangefinder series camera during the late '50. MIR Web Development Team .
