Chinon was among the less innovative Japanese brands, but sold quite some cameras throughout the world in their own name or in others. They were more or less official producers for many others brands during their time, which lasted from 1966 (Chinonflex
TTL) till they were bought by Kodak, Japan in 2004. Their PP SLR production, however, ended around 1989 with the Chinon CP-9 AF. After that, they produced "bridge cameras" like the Gemini series into the 90's, before mass producing compact digital 35 cameras
for Kodak and others.
Chinon was probably the second biggest producer for other brands, after Cosina. Among the brands they made were GAF, Revue, Argus, Prinz, plus some for Ricoh and some for Alpa! And the list is probably very much longer. (But
many Chinon cameras were made by Cosina, according to the Cosina list!)
