e-mail me off list with any specific questions and I will try to answer
them.
Goerz was originally a German company. The Goerz American Optical Co.
became independant of them perhaps as early as the turn of the century.
The original company became part of the Zeiss-Ikon combine around 1926.
Zeiss continued to make some Goerz lenses for a time but never pushed them.
The best known Goerz lenses are the Dagor, the Apo-Artar, and the Dogmar.
All three are well color corrected. The Dogmar was frequently used on
color separation one shot cameras and the Artar was the most often used
lens for graphic-arts color separation work and on LF enlargers for color
work.
The Dagor was probably the most widely used LF lens. Because of its
symmetrical design it has excellent color correction.
