The name Sonnar.
The name "Sonnar" was actually a tradename owned by Nettel Camerawerk in Sontheim am Neckar. Sontheim has the Sun on its Coat of Arms. The Sonnar lens back then was a 4.5 Tessar-type. Nettel merged with Contessa Camerawerke in 1919. Contessa-Nettel was later one of the companies that merged to form Zeiss Ikon in 1926. When the modern Sonnar lens had been designed, Zeiss re-used the old Nettel tradename. — Preceding unsigned comment added by 18.104.22.168 (talk) 17:48, 13 May 2013 (UTC)
