I see Carl Zeiss Jena Sonnar "copies" (1.5-50 and 2/85) on ebay which looks alot like Jupiter-3 oder Jupiter-9 (alloy-body, M39 LTM). Is there a mass-production of "Carl Zeiss Jena" (including the red "T") front-rings somewhere ..?
How do they differ? Other scale ("m" and "." instead of "M" and ",")? You know other signs?
I understand, after WW-2 the Russians decomposed lots of Jena optics for reparation and maybe confiscated lots of lenses. Maybe they also confiscated parts and did the final assembly in Russia.
I will not doubt the optical performance of the J-3 or J-9 which are legal copies of the Carl Zeiss pre-war lenses. But fake re-labeling in the present is another story. If a plain Jupiter-9 is worth 60 USD, why should I pay 180 for the same lense with a fake label?
