Zeiss Coating Question

klop · Apr 1, 2015

I have two collapsible Carl Zeiss Jena Sonnar f2 lenses, both look coated but only one has the red T... Did Zeiss produce coated lenses without the red T ?

Post WWII most of the small optical companies coated uncoated lenses it was the fashion of the time, like selfies are today. The classifieds in AP had a half column of companies competing for your lens.

The coating process needed a prepolish on a nodding machine with an exact radia with a 'final' abrasive to key the hard coating.

Few lenses made pre WWII were coated.

Hi Klop, are they in Contax, LTM or some other mount?
Sorry can't help you with your question. I have one from 1943, #27094##, but it's coated, red T.

They are both Contax mount 1941 and 1936.

Thank you Klop!
Original lens body of my Sonnar was unrecognizable with quite few missing parts. Optical block found happy new home in Jupiter 8 LTM.
