There are a number of importers/distributers currently offering what appears to be the same binocular. Keep in mind, none of these importers/distributors actually make binoculars. Oberwerk, Garrett, APM, AP, General Hi-T, TS, they all import these binoculars. While there is no positive assurance that we have identified all the originating sources, it is a pretty fair bet to say, there are not seven different manufacturers of these binoculars.
Of course it is nearly impossible to tell if they are all "exactly" the same. We know from experience that any particular model line can be custom made for any distributor. As an example, one of the most commonly available large import binocular sizes on the market is the 15x70. You can pick up a Barska, Celestron, Apogee, Oberwerk, Garrett, Telescope Service (or some other brand name) and set them on a table next to each other. At least for some of them, by looking at them you could not tell one from the other. But we have identified probably as many as a half dozen different things that can be done during manufacture to make all these brands different. There is a post in the "Best Of" threads titled "These Look The Same, What Could Be Different?" that addresses some of these differences. Trust me, there are some differences you cannot see.
For instance, no one could ever tell by looking at a binocular if the lenses were produced by a fast machine polish or slow precision polish which is purported to produce a much finer quality lens. No one can tell by looking at a multicoated lens if extreme care was taken to measure the thickness of the coatings to 1/4 wavelength for precision premium cooatings. These are just two major production differences which cannot be seen, but would make a huge difference in performance.
Roland Christen of Astro Physics has stated that he is getting his binoculars from a small operation. From his postings on the process that lead to his decision to carry these binoculars, these are a few qoutes from his comments several months ago. "About 2 weeks ago I received a pair of premium binos from a small Chinese maker which were said to be a direct copy of the 15x70 Fujinons. This sample was certainly a spitting image of that brand. The coatings are excellent all the way through, the eyepieces are nicely corrected over a fairly large field (not perfect at the edges), the spherical correction is miles better than any of the 70 and 80mm that I tested.....This bino definitely has some excellent contrast. To say that I was pleased with these is an understatement......The company that makes them is a small outfit, and they cannot compete on price with the large makers which supply all the normal budget binos in their various configurations."
We know United Optics/Kunnming Optical has had the exact same style binocular available for a quite a few months, and while no one has come right out and stated positively where they are getting their shipments from, it is possible (and IMO likely) that all or at least some of these US and European distributers are getting their supply from the same place.
A review of the United Optics website Series 8 binocular models shows what I believe is this binocular and describes the features that are being described by some or all of these distributors. http://www.united-op...ts/products.htm
All of the following distributors have ads for an uncanily similar binocular.http://www.astro-physics.com/http://www.bigbinocu...com/ultra70.htmhttp://garrettoptica...wsn/page14.htmlhttp://www.generalhit.com./#http://www.telescope...html#1070marinehttp://www.apm-teles...fo.php?id=93736
I can agree with some other's comments regarding this new line of binoculars. With a binocular of such a this level of quality, none of the importers are going to skimp on anything. They seem to all advertise the same high degree of lens polish, premium coatings and rugged build quality. QC from the vendor may be the only variable.
