Look Familiar? (1 Viewer)

Henry,

I was just looking at those in the catalog that arrived today. I'm planning to check them out at my local Orion dealer. Poor Swarovski. But, then, I'm an SLC kinda guy. ;)

Specs give the "linear field of view" as 424.4 lbs......Huh?

I like the way they´re described as having "unique open-bridge design". Not very unique anymore, is it? Do you think they´re made by the same people as are making Hawke and Promaster equivalents?
 
You omitted the price ...

Orion ULX 8x42 ED Binoculars #09256

$269.95

WTF!

Orion ULX 8x42 ED Binoculars
High-contrast extra-low dispersion (ED) objective lenses
Fully multi-coated optics with phase-coated BAK-4 roof prisms
Unique "open-hinge" bridge design, rubber-armored shock-resistant magnalium body
8.1-deg field of view, 7 foot close focus, 17.2mm eye relief
Captive objective lens caps, single-piece eyepiece cap, and soft carry-case included
Click to expand...

There are quite a few problems in the specs too:
  • the 424 lb FOV that Sancho pointed out
  • the 6mm exit pupil (last time I tried it 42/8 was 5.25)
  • "Unique "open-hinge" bridge design": a interesting and novel (perhaps unique) use of the word "unique". Unlike all the other open-bridge Chinese and Austrian bins, I presume.
  • "magnalium body" (that's unique!)

The warranty is different just 1 year (rather than 10 years for the Hawke and lifetime no-fault with a charge (?) for the Promaster).

Unlike the Vanguard EDT these are really ED for $270.

I recognize that 17.2mm eye releif too and the focusing knob design too. So these could be made by Bosma (see the other Bosma ED thread).

That 17.2mm ER also matches Promaster but with a 8.1 degree FOV.

Curiously I just noticed that the Hawke Frontier ED have an ER of 16.6 and that's the same as the OTHER Bosma open-bridge ED bin.

http://www.bosma.com.cn/en/productgn_info.asp?id=980

Are Hawke, Promaster, Orion, RSPB HD all made by Bosma?

There must be more coming. Celestron?

There is a 10x too. Without the 10x tax -- they're the same price as the 8x

Magnification 10x
Optical diameter 42mm
Field of view - angular 6.5-deg
Field of view - linear 341.3
Apparent field of view 65.0-deg
Eye relief 15.2mm

At that price is going to put the cat amongst the rock doves. ;)

Now it seems we need to define "ED" glass. These sure look like the Promaster et. al. Hard to believe that Orion could nearly halve the price with the same glass quality of the Promaster. When does some more widely reconized "name brand" pick this up?

"ED" is already defined: Abbe Number > 80

Perhaps they're just not as greedy as the other brands. Pile 'em high; Sell them cheap?

Wait, didn't we have a thread on this ;)

OK, I guess what I was getting at is this. We see all sorts of binoculars in various price ranges advertising the presence of some high definition glass. It may be called ED, HD, EX, XD, FL or some other nomenclature that may mean nothing outside some marketing ploy or it may signify something to somebody who knows the difference in the glass types. I figure not all of this glass in all of the binoculars that advertise it, is the same quality, or the same type, or even of the same amount or in the same place in the optical system. Hence different price and quality ranges for "ED" glass.
 
I saw these and was very tempted, but I really wanted a porro, so I went with the Nikon SE.

I can only compare one type of "low end ED glass", since I have only owned one. My Celestron 80ED shows no visible CA when viewing (daylight or night), and only the very slightest fringing on the brightest stars when imaging with exposures of longer than 8 minutes or so, with my CCD astro camera. The Orion ED80 garners similar reviews.

For the money, I am extremely pleased.

Again, this is an 80mm scope, not binoculars, but for the price of the Orion bins I may have to take a look. :D

Regards,

Gary
 
It's in the same place ... the best (and only sennsible) place to put the low dispersion glass is in the objective. That's where it reduces most of the color (if you don't suppress CA there then you can't get rid of it further down the optical train).

The other design enhancement is to use Lanthanum Crown (LaK) in elements of the eyepiece to reduce eyepiece stray color (CA).

This is all part of the problem of not disclosing designs (or even as you point out glass types) except in vague ways which are pretty much always marketing ploys.

But ED really does mean something (and is limited to very few glass types and calcium fluoride). And that might be one reason others don't use ED. I'm always rather caution when someone fails to the the term ED or extra-low dispersion in the spec of a bin. But as real ED glass becomes cheaper I think this will happen less.

So in the hypothetical "ideal" bin you might hope to see say a 3 element apochromatic (or 4 element Dialyt) objective including ED glass and an (perhaps 5 element) eyepiece incorporating LaK and an aspherical element to keep the field flat. Sounds a lot like the Pentax ED bins ;)
 
Although binocular may have the same outside look, what's inside is what really matters. I suspect this binocular might just copy the style from Promaster Elite with different optics inside. Only when someone get a copy in December and test it out, we will find out if it is a real deal, or just another "junk" from China. Frank, we are looking up to you on this.;)
 
I doubt that the Orion binocular is a copy of the Promaster from a different source. The bridge parts look identical, so I think it's likely that the same manufacturer makes both. It could be a cheaped down version or Orion may just have a pricing advantage since it's both the importer and the retailer.

Not much point in trying to track down what type of glass is used in any of these variants. There is apparently an "ED" type glass (H-FK61) available in China now said to be no more expensive than normal glass, so why shouldn't it turn up in cheap binoculars? What matters is whether a particular objective design using some type of ED glass actually has less longitudinal chromatic aberration than to a conventional objective. We're not helpless to determine that for ourselves. In normal use it's nearly impossible to see longitudinal CA in any 8-10x42 binocular, but it's easy to see if the magnification is significantly boosted. All that takes is placing a small binocular or scope behind the eyepiece of the test binocular. At 64x (an 8x bin placed behind the eyepiece of another 8x bin) it will be obvious whether or not the "ED" glass is accomplishing anything.

If someone checks out the 8x here, I might then be interested in the 10x version. What is the Orion return policy?

Speaking of looking familiar. I wonder who the Bushnell Excursion ED manufacturer is. The Excursion looks very similar to the Promaster family. Not identical to the detail the Orion appears to show, but similar enough to maybe be from the same OEM (maybe). I did notice what I thought of when I had the Excursion EX 8x36 in my hands that that was what I thought a smaller version of the ELX ED would/should/could feel like. Now back to the store to see if there is an Excursion EX 8x42 on display. I was more "focused" on comparing some other glass to the Promaster, so I never thought to look for an EX 8x42.
 
Steve: our previous "tame Chinese OEM" on the Hawke thread implied (rather strongly) that the Vortex Diamondbacks and the Bushnell Excursion are the "same" bin made by the same group (i.e. his OEM, I presume). And t same is true of the Excursion and Excusions EX (not ED yet ;) ) with same/related optics in different cases.

So that said that his OEM makes some Bushnell, Vortex and Hawke. Plus he seemed to have made measurements on the Promaster. That could be another OEM or it could be his. Of course he never answer my direct question of who he worked for ;)

Another point is the Repellmax coatings on the Promaster. Bushnell has been working on these coatings and is licensing them to other manufactuers (including Zeiss ... I presume Bushnell got the patent in first or it's a cross-licensing deal to avoid litigation!). If the factory is already set up to add the coatings for Bushnell it makes it easy to add them for other OEMed bins (and Bushnell in the Zeiss licensing announcement said they were looking to license it broadly).

I think there is one Chinese OEM (who might not actually be making bins but just making enclosures) is making this Mg open bridge case.

Then others make the knobs (that knob design appears on several bins including the Bushnell Elites I think).

So you can expect to see these bits change (every brander wants to look a bit different though most of the difference is in the rubber armor molds and the badging - those are easy to change).

But of course only the rebranders (in the US) and the OEM/ODMs actually know.

But given the same ER numbers keep popping up I think there is a lot of shared optical design here.
 
It may take a few months for me to sell some other junk. I am getting clutter in the closet and under the bed..mostly scopes and tripods. I really hate tripods. I have three.
 
Kevin,

Had that thread in my mind. Now, what I'd like is to see the Promaster ELX ED optics show up in the Bushnell Excursion EX 8x36 package. I'd own something like that pretty quick. I wouldn't particularly care if it was a Promaster, Hawke, Orion, Vortex, or a Bushnell. I really like the Promaster, but there are times when a little smaller would be really nice. While I'm wishing, I'd really like a 7x36.

NW,

Sorry bud. I am pretty much tired of all of these open bridge style ED glass bins. Now if they make one the size, shape and weight of something like a Pentax SP or Nikon Monarch (without giving up the wide field of view, brightness or sharpness) then I will be the first in line with a credit card. For now the Orion can be somebody else's baby.

;)
 
Bosma are making one ED with a "closed-bridge" but I don't see many taking it up (except the RSPB HD).

And it seems if any of them make 32mm ED bin that "closed-bridge" is much more sensible design: I want some place to put my fingers. Though I could see them making a 36mm OB (like the Bushnell Excursion EX) as they seem to already have the enclosures designed.

I suspect after a couple of years well see open-bridges like fins on cars: an interesting idea taken to an extreme.

Bring on the 32mm and 36mm Chinese EDs. In 2009 perhaps.
