A couple of days ago I came upon a thread that linked to an excellent write up and schematics for pre war wide and ultra wide Zeiss lenses from the 30's and 40's.
Of course, I forgot to "favorite" it and now I kind find it! Does anyone know what the hell I am talking about. I think one of the lenses was the Spheregon(?).
Thanks in advance

Was it this Zeiss blog ?
"Did you know that the common suffix “gon” in Distagon, Biogon and Hologon means these are all lenses with a large angular view? “Gon” comes from the Greek word “gonia” for “angle.” Like many other manufacturers, Carl Zeiss uses a common end syllable to create consistent naming for its wide-angle lenses. One of the earliest examples of this approach is the famous “Hypergon” from Goerz which had a 130° angular view. That created lots of excitement at the beginning of the 20th century, as did the later three ZEISS lens types Distagon, Biogon and Hologon."

This might be the same as Mr. Freeze provides; interesting that this was published n Dec 2011. These papers from Zeiss are interesting I've read two others that now I cannot remember or find!

Yes it is the same. I see now that RFF shortens the long urls.

There's a very promising link in that thread to http://www.marcocavina.com/articoli_fotografici/Perimetar_Sphaerogon_Pleon/00_pag.htm
And other interesting stuff on that site such as the Zeiss 50mm f/0.7 http://www.marcocavina.com/omaggio_a_kubrick.htm

Thats the one I was looking for - the Marco Cavina set of drawings! Amaxing lenses.
Thanks to verybody - now I have to learn Italian to read the fine print. I mainly wanted it for the look of the optical designs.
