Projection lens made for Emo, by Seibert of Wtzlar West Germany.
Information from Martin Tai (http://photo.net/minox-camera-forum/003HX0?start=0)
Arthur Seibert (
1906- 1980) was
Ernst Leitz lens designer from 1920 to 1947.
In 1948 Seibert left Leitz and undertook the task
of designing a subminature lens for Minox camera .
Arthur Seibert was a great optics designer, his most famous designs were the five element Pentar lens of Minox II and the COMPLAN lens for Minox III/IIIs/B, and early Minox C. The Pentar and COMPLAN are still two of the sharpest subminature lenses-- in fact the sharpest of any commercial photographic lenses
In 1951, Arthur Seibert formed his own optik company
This lens was designed for 16mm film projector. Usually such lens only has sharp in center. But this lens has sharpness in edge too, like Kern 75/2,8 cmount.
