The most Pentacon brand lenses were derived from classical East-German lens constructions. When the Pentacon combinate (Pentacon group) was founded in 1968 the famous German lens maker Hugo Meyer in Görlitz (since 1952 officially "VEB Feinoptisches Werk Görlitz") was incorporated into that group. The lens maker's brand name was changed from "Meyer Görlitz" to "Pentacon", and even Meyer's renowned trademarks like "Lydith" and "Orestor" were omitted. Since then all the successful former Meyer lens constructions were produced by Pentacon. Further lens development focused on the lens coating's improvement, resulting in advanced Pentacon lenses with "multicoating" (MC). When the era of zoom lenses began Pentacon started trading rebadged OEM products. The camera trademark "Exakta" even seems to have been borrowed by Japanese lens makers for marketing standard zoom lenses for several popular lens mounts. Thus these "Exakta lenses" were neither Pentacon constructions nor Pentacon products.
