Topogon

Topogon is a wide field (originally 100 degrees field of view), symmetrical photographic lens designed by Robert Richter in 1934 for Zeiss Carl FA.[1] Lenses produced under the name Metrogon also cite the US patent of the Topogon design.

Topogon lenses have been produced in f numbers ranging from f/3.5 to f/15 in various focal lengths.[2]
