Originally posted by ivanvernon Thank you for your comment. According to my understanding, the Arsat 30s and Practicar were made in Ukraine, but the Carl Zeiss Jenas were made in the original Zeiss factory in Jena, East Germany, hence the use of "Jena" .
The Arsatwas made at Arsenal Works (or following up workshops) in Kiew, Ukrainia . Prakticar is a brand of VEB Pentacon. Most Prakticars were made at Feinoptische Werke (FOW) H. Meyer, Görlitz ( Niederschlesien) . Görlitz is a town in state of Saxony near the polish Border. In late 1980ies photooptical workshops in the former GDR were concentrated in the VEB Pentacon, Dresden brand , which was part of the VEB Carl Zeiss, Jena combinate (concern). But most of the Prakticar lenses were manucfactured in Görlitz and were Meyer constructions, some in Bukarest at FOM (e.g. the Standard 1.8/50mm Prakticar for 135 Cameras). Up from 1985 only some were made at Carl Zeiss workshops in Saalfeld (Thuringia) (eg. Vario-Pancolar/Vario Prakticar 35-70mm, Vario Sonnar/ Vario Prakticar 80-200mm). In the End of the 1980ies all Prakticar -B lenses from VEB Carl Zeiss for 135 camaras were labeled as "Prakticars", till the mid 80ies these lenses had still the tradional Zeiss names (Flektogon, Biogon, Biometar, Pancolar , Tessar, Sonnar, Vario-Pancolar, Vario Sonnar) The label for medium format lenses were never merges till 1990. The labeling was Prakticar = VEB FOW Meyer, Görlitz; Flektogon, Biometar, Sonnar = VEB Carl Zeiss Jena, factory Saalfeld.
