Question for the group: I have2 Automats with 3.5 Tessars. One has the expected Opton-Tessar, coated, but the other, a bit older, Very different, has been re-lensed with a Carl Zeiss Tessar, a much newer lens. My question: the CZ tesar beats the daylights out of the Opton. what was the difference in formula between the coated Jena 3.5, coated Opton 3.5, and the later CZ 3.5? Is this a better lens, or just an individual in better condition?
