The Sonnar was designed by one of my lens design heroes, Ludwig Bertele. Ludwig Bertele worked at Ernemann, and later Cal Zeiss, when Ernemann was later merged alongside three other companies (Ica, Görz, and Contessa-Nettel) in 1926. From what I can tell, Bertele is nothing short of a genius.

The work of Ludwig J. Bertele played a key role in the rapid development of geometrical optics and thus photography after the First World War. Later, his designs also set new standards in aerial photogrammetry and other specialized fields of optics.
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.
