Enna factory
The Enna factory in Munich was founded in 1920 by Alfred Neumann. The name ENNA was made up of the first letters of the company's founder. After his death, the company was taken over by his son-in-law, Dr. Werner Appelt, continued.
ENNA was a manufacturer of camera lenses and projectors . In 1958 the world's fastest wide-angle lens for SLR cameras Super-Lithagon 1.9 / 35 mm and in 1961 the world's first telephoto zoom lens 4 / 85–250 mm was released.
ENNA became known for its automatic base system for Edixa , Praktica , Exakta and Exam models with lenses of various focal lengths, which it offered from 1958 . The lenses were sold under the brand names "Ennalyt", "Lithagon" and "Revuenon". Enna has also built lenses for Photo Porst and Foto Quelle (Revue).
At the 1972 Olympic Games in Munich, lens production at ENNA experienced another boom when the company was one of the "official" suppliers and was allowed to decorate its products with the 5 rings. After this time, ENNA shifted more and more to the development, construction and manufacture of technical plastic parts in small and large series, initially in the field of photography. So slide mounts, slide magazines, slide viewers and similar products were made.
The ENNA plant Dr. Appelt GmbH & Co. KG still exists today, in Wegscheid near Passau. The production program still includes slide frames and cases today. But the company's own toolmaking, assembly and surface finishing are also part of the company's portfolio.
