Interesting Zeiss Article about Tessar Design

[david.elliott]

Looks like Zeiss is putting up a series of articles about the various lens designs and their names (tessar, sonnar, planar, etc).

Here is a link to the article about tessar lenses:

• General link to the page (which links to the pdf below)
• direct link to the PDF article itself

An interesting read for sure.

A Leitz Elmar is pretty much a Tessar. You can eliminate all the main aberrations with the four elements; its main limitation is maximum aperture; you really need six or more elements to get to f/2.
