Voigtländer was an optical company founded by Johann Christoph Voigtländer in Vienna (Austria) in 1756 and is one of the oldest brands in photography. The company moved to Braunschweig (Germany) in 1849. In 1965, Voigtländer merged with Zeiss, and the Voigtländer brand was sold to Rollei. After the collapse of Rollei in 1982, a company named Plusfoto GmbH & Co took over the brand, selling it in 1997 to Ringfoto GmbH & Alfo Marketing KG. Today, Voigtländer does not design or manufacture anything, it only exists as a brand name. Since 1999, Voigtländer-branded products have been manufactured and marketed by Cosina.
Through its more than 250 years of history the company has produced many different photographic products, but historically, the brand is best known for its 35mm and medium format rangefinder cameras and premium manual focus lenses for 35mm SLRs and M-mount rangefinders. Late in 2010 Cosina announced the first Voigtländer lens for the Micro Four Thirds system, the 25 mm f/0.95 Nokton.
