The Spring 2013 issue has Ottos, Ghisettis, Cavinas, and Benjamins along with detailed write-ups about the Werra, Aseros, and the Zeiss Planar. That’s a lot of Zeiss!
Pg 2. While the Tessar might be Zeiss’s most popular lens design, the Planar is not only older, but just as significant.
Pg 6. Werra – The design miracle from Eastern Germany.
Pg 13. The Aseros is a zoom telescope from the 1920s.
Pg 15. A book review of Carl Zeiss Kamera Registrer 1902 – 2012 by Bernd K. Otto.
Pg 18. A book review of The Contarex Book by Pierpaolo Ghisetti and Marco Cavina.
Pg 20. An 1890 catalog supplement expressed doubt about the durability of Zeiss Apochromat microscope lenses, and it turns out, they were right!
Pg 22. The Optovar is a magnification changer accessory for some Zeiss microscopes offering enhanced magnification.
Pg 24. In 2013, Canada issued a new $100 bill featuring a woman using a Zeiss microscope. Cool!
