This is reputed to be the best lens of the Contax line after the mythical Biogon 21mm.
In fact it's so good that it's design passed nearly untouched to the postwar Jena version for M42/Exakta and the early 60s west Zeiss version for the Contarex,
where it sold much better than the 2.8/135 Sonnar which costed only a little more but was one stop faster. This says a lot I think.

You're welcome! I was never able to buy this lens. I could only buy the Soviet copy Jupiter-11,
but alas, it isn't even only half as good as the original Sonnar Sad
Since the lens design is very simple, I must conclude that it's the quality of the optical glass in the Zeiss lens
(and the production control as well) to make the decisive difference.

Isn't Contax T a compact camera?

I think you mean same lens , but with RED T coating. What I did show before Opton-Tessar 135mm f4 , right ?

Difference I think better coating only.
