3 generations Pentacon 1.8/50 image by TrueLoveOne (Image rights) |
There are 3 different versions of the Pentacon 1.8/50. In the picture on the right you can see from left to right: the orginal rebranded Meyer Oreston, the re-designed "red mc" version, and the final version with green printed scales.
Optically only the first one is slighly different as it has only a single coating applied. The other two, marked Multi Coating, do have an improved coating on their glass elements.
