Zeiss Sonnar
(重定向自Sonnar)



The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture.
The name "Sonnar" is derived from the German word "Sonne", meaning sun. It was originally a tradename owned by Nettel Camerawerke in Sontheim am Neckar for a 4.5 Tessar-like lens. Sontheim's coat of arms includes a symbol of the sun. Nettel merged with August Nagel's Contessa Camerawerke in 1919. The resulting Contessa-Nettel AG in Stuttgart was one of the companies that merged to form the Zeiss Ikon AG in 1926.
