The Flektogon was an early wide angle lens of its type with a short focal length yet a long back focus distance (although the cine retrofocus design of Angénieux preceded it). It was introduced in 1950 by VEB Carl Zeiss Jena, the East German Zeiss optics plant. The first variant was the Flektogon 2.8/35 for 35mm SLRs. Later other 35mm variants were made: 4/25, the remarkable fast 2.4/35, the first super-wide angle lens 4/20 (1961) and the outstanding Flektogon 2,8/20 (1976). From 1978 lenses were also made for the bayonet connection of Praktica B-series with the name "Prakticar".
Medium format variants were made for the Pentacon Six: 2.8/65 and 4/50.
Other lens makers like Carl Zeiss Oberkochen (West Germany) made similar lenses like the Distagon. It's a rare case of an eastern product copied in the West. Production of the manual-focusing Flektogon ended in 1991 whilst the Distagons are still in the market. A new variant by Carl Zeiss is the autofocus Flektogon 1:3,5/35mm for the Rolleiflex 6008 AF.
