Flektogon
The Flektogon 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 and the first super-wide angle lens 4/20. Medium format variants were made for the Pentacon Six: 2.8/65 and 4/50.
