The name Jenoptem indicates that it is a fairly late model, as Zeiss West Germany was able to get sole rights to the Zeiss name after the country was reunified.
Do note that there was extensive production in Japan of copies of the 10x50 especially, reportedly by virtue of a licensing deal. Many of those have the Japan inspection sticker and a 6 digit serial number, while all Jenoptems should have a seven digit number starting in 6 or 7.
Bitterroot's comment on pricing is bang on. These binocs are a great buy when in good condition.
The Allbinos site has a recent review of the 8x30 DEltrintem, the kid brother to these.
They still are excellent optics.
I have always heard the six-digit Jenoptems were plain fakes and had nothing to do with Carl Zeiss Jena. They certainly did not have the quality or build of the genuine 7 digit Jenoptems.
I don't know what is meant by fairly late model, but most multicoated Jenoptems were manufactured in the 80's. Those not marked multicoated were older. The 8X30 Deltrintem and 8X30 Jenoptem were identical in performance and specs, the only difference being manufacturing techniques (automated production with the Jenoptems) used, leaving the Jenoptem as less expensive, but not necessarily lesser in quality.
Due to litigation over the Zeiss name, Jenoptems were imported into the U.S. under the "Aus Jena" brand name rather than "Carl Zeiss Jena" as they were marketed throughout most of the rest of the world. Only the Oberkochen (West German) Carl Zeiss binoculars were allowed to be marketed as "Carl Zeiss" binoculars in the USA during this time period. If you have a pair of Carl Zeiss Jena Jenoptem marked binoculars, they were likely originally sold in another market (like England).
Carl Zeiss Jena eventually was purchased by Docter Optics, and it exists that way today, where the famous Carl Zeiss Jena Nobilem models are still produced as Docter Nobilem binoculars.
The history of Zeiss is fascinating. I recently read a concise and complete history of the company online. I will try to find it again and post the link.
I received my mid-80s Jenoptems last week (from England) and they are truly wonderful little binoculars. Those multicoatings were way ahead of their time.
