A version of this lens has the front lens ring marked "T2.8/50 aus Jena DDR" plus the serial number. The feet markings on the focus ring are red, and the right hand "4" on the depth-of-field indicator is white, with a red dot above it.

As the result of a 1968 American court decision, the West German Carl Zeiss Oberkochen won the exclusive right to use the name “Carl Zeiss” in the USA. Carl Zeiss Jena then exported its lenses to the USA with the marking “aus Jena”, meaning “from Jena”, instead of “Carl Zeiss Jena”. The West German firm may also have had the exclusive right to the "Tessar" designation, hence the "T" on the East German Lenses.
The Optical quality is equal to those lenses marked "Carl Zeiss Jena"
