Carl Zeiss Jena “Deltrintem” 8 x 30 binoculars serial number 7300856. These binoculars, with their very high serial number, are probably some of the very last Zeiss glasses ever to bear the world-famous doublet lens “Carl Zeiss Jena” Kuithan logo introduced in 1904 .They were manufactured in 1991, after the re-unification of Germany, at the former DDR Zeiss plant in Eisfeld, near Jena. Later that year the company was sold to Docter Optic who continued production of the model but under their own brand. Gone is the “Made in DDR” script, replaced by “Made in Germany,” found on all Zeiss products until 1945. And in this “transitional” model certain new features, which were to be carried over to the Docter version, have already appeared, namely the new pattern cast-alloy focus wheel and matching outer eyepiece shells, together with foldable rubber eyecups. The Deltrintem itself, introduced in 1920, was one of the most successful ever Zeiss models, a truly versatile compact binocular. And the addition of T3M multi-coated optics, introduced in 1976 by Zeiss DDR as a world first, made it even more popular as the ultimate “all-purpose” glass. Optical condition of these binoculars is excellent for an original, un-restored example. Internally they are crystal-clear, totally free from fungus and haze. All lenses, prisms and optical coatings are pristine and unmarked and collimation is perfect, no trace of a double image. Cosmetic condition is likewise excellent, relatively new binoculars which have had little use, with just a few signs of usage. So an historic binocular which, I hope, will find a place in a collection of this great marque. Sold with original top-loading “luxury” case, case strap and lanyard. For full technical description please see Zeiss catalogue page included in the photos (for the similar pre-1991 version). The binoculars will be very carefully packed in a well padded box for dispatch and sent fully insured. I never end auctions early so there is no “buy-it-now” price. Postage:- UK Royal Mail First Class Signed 6-55. Europe Royal Mail International Tracked & Signed 12, rest of world 17. Payment or email contact required from the winning bidder within 24 hours of auction end. Please see my other binoculars for sale – reductions for combined postage, cheapest item free.

Introduction

This catalogue was distributed by binoculars dealers in UK,probably around 1985, because it contains the then newly introducedPorro prism models 12x50 Dodecarem and 8x50 Octarem,later renamed 'Nobilem'. While these represented the rather expensive high end line of the Zeiss Jena collection, the classicalline, containing the 8x30 Deltrintem, 7x50 Binoctem and 10x50 Dekaremwere Jena's actual working horses of that time. They were of very decent quality and, produced in the DDR, took profit of the favorablecurrency exchange rate to be available for a highly competitiveprice. During these golden times, Carl Zeiss Jena was able to produce 200,000 binoculars per year!

What is special about this brochure (and in contrast to the German version)is the fact that it offeredtwo representatives of this classical line, the Deltrintem - Binoctem - Dekarem, as well as the corresponding Jenoptem models.Apparently, these were identical in construction, and any dealerfound himself in the delicate situation to explain to the customer the factthat a 7x50 Jenoptem was cheaper than a 7x50 Binoctem, withoutbeing able to point out any particular difference in performance.In fact, the catalogue avoids mentioning details regarding this paradoxon, just explaining that 'The only difference is in the manufacturing techniques utilized in the two models. This does, of course, mean that the Zeiss 7x50 Jenoptem reallydoes represent outstanding value' (page 6). This soundslike: 'Well, we have got twice the same binocular for you. Oneof them is produced more efficiently than the other and istherefore cheaper. Its your choice...'.

In what follows I shall give a few remarks on whatever else I found interesting in this brochure.

Additional remarks:

Page 3: This introduction appears quite informative and reasonable.Instead of the hype and exaggeration about the unbelievable performanceof their products, as often found nowadays in advertising brochures,Zeiss Jena provides a rather sober overview of its production lineand the intended spectra of application.

Page 4: The Jenoptem displays the trademark 'aus JENA', printed onthe left prism housing. After a legal battle with Zeiss (West, Oberkochen),Zeiss Jena was prohibited to use the Zeiss trademark on products exported to certain Western countries, among them the U.S., but,to my knowledge, not including England. This catalogue uses theCarl Zeiss Jena trademark throughout, but strangely doesn't show iton the instrument itself.

Page 6: The plot shows a cross section of the Jenoptem 7x50 with asimple ocular construction of 3 (?) lens elements (the 'plate' facingthe prism seems to indicate the position of a reticle only, as it wasprovided with some of the binoculars), which seems to be correctfor the 7x50, whereas the 10x50 had got more sophisticatedwide-angle oculars.

Page 14: The Dodecarem is touted as 'New', which indicates thatthis brochure was printed around 1985. It shows the same, rathersimple ocular construction of the 7x50 Jenoptem, which is incorrect,since the Dodecarem, like the Octarem, came with 4 lens elements (see also here for a detailed plot of the Octarem published 1985 in the Jenaer Rundschau).

Page 16: They confuse '8x50 Dodecarem', which supports the claim thatthese binoculars were probably newly introduced.

Page 18: This is of course the civilian version of the EDF 7x40 ofthe NVA. It is interesting to note that the catalogue does not mention its military origin. The ocular construction looksidentical to the Notarem's (Page 10), but this seems to beincorrect, as this more detailed plot suggests a 5 element Erfle construction instead. The remark 'Built-in Umbral filters act as protection against strong sunlight'refers to the strong yellow tint of the EDF. In reality this was notproduced by any filter, but the result of special radiation resistantflint-glass types in the oculars; see here (in German language) for a more detailed discussion on that.

Page 20: The Octarem is specified with a field of view of 122m/1000m.However, on Page 17, the same specification is given as 130m/1000m. This confusion has never been sorted out since then.Even nowadays both specifications are found for the Octarem or itssuccessor, the Nobilem. The 8x50 Nobilem which I have tested hasdefinitely got 130m/1000m.

Remark: After the collapse of the DDR, the Zeiss Jena plant wastaken over by Docter Optic. A set of their product leaflets of the early 1990s shows that most of the Zeiss Jena binoculars were still made under the Docter label, some improved versions of them are produced even today.
