Zeiss and Voigtländer integrated in 1965. In 1972 Zeiss/Voigtländer stopped producing cameras, and a year later Zeiss sold Voigtländer brand to Rollei. On the collapse of Rollei in 1982, Plusfoto took over the name, selling it in 1997 to Ringfoto. Since 1999, Voigtländer-branded products have been manufactured and marketed by Cosina.
