Andrea B. Posted February 27, 2017 Share Posted February 27, 2017 These are such good flowers for UV-Vis-IR comparisons, aren't they? I like the delicate tones of the IR photograph with that pretty false yellow. Tell me please, what is the brand of your Tessar 50/2.8 lens? Is that a Zeiss? A Carl Zeiss? Link to comment

Either way, they are both the exact same lens. The only difference is that at the time of production Carl Zeiss Jena (East Germany) did not own the copyright to the name Tessar which was also being produced in West Germany by Carl Zeiss Oberkochen among others. This tends the less expensive version".I have the aus Jena T DDR version, the cheap one :-) Link to comment
