CARL ZEISSJENA binoculars were produced in the old EAST GERMANY (DDR). This listing is for a 10 x 50 `JENOPTEM` binocular dating I believe from the.
The binocular arrived out of collimation, as usual with used items. Looking at its picture on Ebay, I noticed that the screws of the prism covers had the head bigger than the usual, but didn’t attach any importance to it. When the binocular arrived I discovered more alarming details, and understood the body wasn’t that one I knew for having repaired dozen s of DDR binocs. The focus knob was not metallic but in plastic; the eyepiece assembly was very different from the typical one of CZJ 10×50, was poorly built and with three screws setting the right eyepiece ring instead of the retaining ring used by the DD R factory in the Jenoptem series.
Also the central focusing system was very poor, floppy and with the classical sticky grease used to reduce mechanical deficiencies. Moreover, there were set screws through the body to tilt the prisms, and this despite the presence of eccentric rings and cups. These were as roughly built as every part of the body, with one notch of atypical and not practical shape on the eccentric ring and no one on the eccentric cup.
I have seen very few binoculars with double collimation adjustment, and I seem to remember that in all those cases set screws had been added by technicians with neither patience nor probably knowledge to adjust the parallelism just by using the eccentric rings. Nevertheless, set screws were certainly original in this binocular.
Antique and Vintage Binoculars
I prefer solidly made binoculars, and have amassed a modest little collection of prized specimens, mostly acquired off eBayUK, but also charity shops and car boot fairs. I used to own a pair of 11×80’s bought off Leo Henzl Jnr in , but I sold them 10 years later. They were too heavy to hold for more than a couple of minutes, and on a photographic tripod, too awkward to point near the zenith. You really need a parallelogram mount for binoculars that size and larger.
I prefer a binocular you can carry with you to a star party, for casual star gazing.
CARL ZEISS STAND #1 Stage of ZEISS Microscope Zeiss substage This particular model of binocular accessory dates from after , as an earlier model.
They were made in 4, 6, 8, 10, and 12 powers together with a similarly built Jagdglas in 5 and 7. During this period they underwent numerous modifications resulting in variations some of which are – 1 Font: From to all markings were in cursive script whereas afterward most models were marked in Roman font.
By Thomas Antoniades. By Thomas Antoniades — Excel file. The original markings on this binocular have been badly worn or intentionally removed. Some portions appear to have been either expertly re-engraved or else left intact if the other markings were intentionally removed. The original markings on the left prism plate were: Carl Zeiss, Jena over D. The original Zeiss serial number, , is marked on the bottom edge of the right hinge plate.
As detailed by Mr. Antoniades, Zeiss binoculars manufactured between were serial numbered according to model and magnification, and Zeiss serial numbers did not become generally sequential for all binoculars until Thus, although according to a generally sequential serial number table the binocular appears to have been manufactured in , it was actually made in
The ZEISS Archives
The current study supersedes my very first attempt at establishing the facts, concerning the above, back in June Since then I have learned a lot and look back in shame at my pronouncements of the time. I stand to be corrected in everything I write and offer this edition knowing and expecting to be corrected. As with other attempts at resolving or just shedding light on the problem, no sooner has the ink dried on the version about to be published, one then realises that all is not quite so final.
With each day that passes, however, and with new numbers becoming available the jigsaw pieces fall a bit more into place. It supersedes all previous editions the last one being that of 29 th December
Vintage 8x50s from Carl Zeiss Jena and Oberkochen Firstly, the date of the issue of that directive is unknown to him, but it was definitely the first time his father.
This guide is in response to the number of fake or non-genuine Carl Zeiss binoculars being sold on Ebay. It applies mainly to the Zeiss Jenoptem 8×30 or 10×50 binoculars and on rare occasions to the 7x These were sold mainly from mail order catalogues in Britain in the late 70s to early 80s. Wether they were contracted out by Zeiss to Japanese makers or just fakes is difficult to ascertain today. Main point is they are very inferior to the German made article and do not survive constant use.
If the bino is a Jenoptem in the above sizes and has a six figure serial number it is not German made. Equally if it has any letters in the serial number it is a fake. Genuine binos always have a seven figure serial number. The focusing wheel will be black plastic and has a ring impressed into the front.

Notes: In when Germany was partitioned by the Allies, Carl Zeiss personnel separated and formed two different companies. However, Zeiss senior management and scientists with American assistance were moved to Oberkochen in West Germany to subsequently manufacture binoculars under the name Carl Zeiss. The first of these was this 8×30 introduced in It is an extremely light-weight and compact wide-angle binocular built around 2 element air-spaced objectives to reduce focal lengths and having small objective prisms and asymmetrical ocular ones with six element eyepieces to give a wide-angle view.
The above example has flexible rubber gaskets sealing the ocular housings as the binocular is focused, a feature added in

Summary: A civilian eye focus Zeiss dating back from the early 20th century a collectors item more than a serious contender today. If clean and in good condition.
In these models, however, we can best see the evolution in design, and small production changes that took place until the end of World War I. It is my goal, to help my fellow collectors to appreciate their collectors items, and be able to observe the different phases in production as far as I can distinguish them.. I appreciate that not everybody may be concerned with all the details of his particular binocular and he may be just happy to display it. In this context my notes will be yet another example of the gathering of information on a subject nobody is really interested in or cares about.
I have, however, found the recording of the subtle and not so subtle changes that took place, helpful in examining the binoculars of the World War I period and establishing whether they are genuine or mixed together with different parts from different binoculars whether in the trenches or through the hands they have been passing through later on until they found their place in someone s collection. Binoculars have at all times been mixed with parts from other binoculars, and sometimes not even of the same kind of binocular or the same producer.
