Additional information:
The Schneider-Kreuznach Edixa-Tele-Xenar 135mm f/3.5 is a telephoto prime lens for 35 mm SLR cameras with the M42 screw mount.
Today the lens is rather expensive and popular. Its optical design is different from that of the analogous lens for the Rollei SL35 system, which is the later enhanced lens. Despite the fact, the M42 version is more appreciated because of a larger compatibility with modern cameras and is more expensive.
For Edixa M42 screw mount cameras the lens came in three basic modifications different in appearance (exactly the same as for the rest Schneider line-up):
I - thick "zebra", massive ribbed rings - most common version, manufactured from about 1960 to 1965 [photos 1-3]
II - thin "zebra", plain rings - rarest version, manufactured for a year from 1965 to 1966 [photo 4]
III - ultimate, all black, artificial leather coated ring, manufactured from 1966 to the late 1970 [photo 5]
It is most likely that it is not only the lens' exterior that had been changing, the optical scheme had slightly changed as well. But the exact information is difficult to find now.
