Does anyone know if there is a difference between a Goerz Red Dot Artar and a Goerz Apochromat Artar. The Goerz Red Dot Artar really say: CP Goerz....Apochromat (red paint dot) Artar.
The only difference I can see is a red dot painted between the two words Apochromat and Artar. Why can't a person put a gold or green dot there and call them "gold dot" or "green dot"? Maybe a "purple dot"!
Anyway, is there a difference between these lenses or did the dot get rubbed off?
