hi Tero! ^_^

do you think the bino in my attachment is jb-22?
no image of jb-22 at pricerunner ...

and that exit pupil in 8x30 model (in spec I wrote) is wrong...I just did copy-paste on that spec...^^

are these ''made in Germany'' ?? cause I can get it for about $40...seems good price...^^

best regards

Jenoptik is I believe a new brand seeking to benefit from the luster of Jena, which had been the home for Zeiss pre war.
After Germany was reunited, the Zeiss name became sole property of Zeiss West Germany and until the Zeiss Jena binocular operations were taken over by Docter, the Jena production was sold under the "Aus Jena" (from Jena) or "Jenoptik" names.
Once Docter took over the Zeiss Jena binocular plants, Jenoptik lost any connection to the Zeiss heritage or facilities, at least as far as I know. Imo, Jenoptik today is a marketing name for low cost binoculars of international provenance.They market a range of middling binoculars, most notable for their unusual shapes and colors. I've owned a couple and sold them with no regrets. I do not think they are German made or even assembled in Germany from foreign parts.
 
Hi Yippeekiay,
Very interesting posting. Valdad is presumably the US distributor for IOR,a Romanian optics manufacturer that produced Zeiss Jena near replicas with the same Schott glass types used by Zeiss
The Jena binoculars shown look exactly like the range offered by Docter, the firm that took over the old Zeiss Jena plant. I've owned their 12x50 Nobilem, a splendid glass and the 7x40 EDF is likewise a legend among military binoculars. It is possible that Docter has licensed IOR to produce these designs, or has just sold them the business. Docter's primary market is industrial optics applications, so the consumer binocular line was never a mainstream business for them. It seems like musical chairs is not unheard of in European business either.
Any new reviews of the Valdada line would be very interesting. The 15x60 Docter version was well reviewed because of its fine optics, but got dinged for its near 4 pound weight. I don't think any of these big porros are waterproof, but they are rubber armored and will shrug off a normal rain, at least in my experience.
 
Hi,
Good news, 7X40EDFs coming back. If they keep their outstanding night performance, for wildlife no astronomy, I'll consider a pair. Hoping review of any user.

While the 7x40EDF has excellent low light performance, its appeal has been reduced for civilian use by its IF design as well as by the noticeable yellow cast of the image. Hopefully the yellow glass, which was allegedly so formulated to resist darkening due to radiation exposure, has now been replaced by a more peacetime specification.
 
That would be cool. I have a pair of KOMZ BPO's and the yellow definitely detracts from some forms of birding like warblers and such. Raptors, however, can't hide from them. Even at more than a mile and a half (googled distance). Plus, I never did find IF oculars all that bad. Just have to hold them differently. Even w/ my Fujinon 7x50's the DOF what such that refocusing was infrequent.
As much as I'd LOVE to try the EDF's, $1200 just isn't in the cards. Maybe it's time to start a new fund. :t:
Likewise, I'd love to see some reviews on these.
(Oh, I'm pretty sure the Jena porros are waterproof )
