Rolleiflex was known for the two eyed SLRs from earlier years, but went into the PP SLR business around 1970. Like other West-German brands at the time, they were struggling with the Japanese domination, and moved the production to Singapore to survive.
They took over Voigtländer from the falling Zeiss Ikon in1973, making parallel cameras in two brand names and with two different mounts, the M42 for the first Voigtländer VSL-1 (TM) and the bayonet-mount (BM) for Rolleiflex and later Voigtländer
VSL models.Their market share was mimimal. Besides, some mention that the quality control was not good enough. Others deny this. Anyway, Rollei did not make cameras that were interesting enough to the public, and the brand ended in 1982.
