Good questions. I don't know the answers. Just asking people to take into account that this forum is a subforum of a birdwatching forum probably won't work.

It would certainly be smaller than the current forum. Just look at the threads, there are plenty that are plainly not about using binoculars and the properties they should have (shouldn't have) for birdwatching, how they work in the field and so on. To my mind they are off-topic here.

Right, and that's how it should be. Mind you, I sometimes think some of the "advice" given here is more based on hearsay or some impressions gained at a quick visit to a store rather than actual experience in the field. And quite a few "reviews" beginners may read here probably aren't based on solid experience either.

There would of course still be technical discussions - but with more focus on what the technical details discussed actually mean in the field. In real life. In fact, if you go back 10 years or so there were probably more technical discussions than today.

I know. I miss those technical discussions. It seems like me and Henry Link are the only members left with any technical expertise. Most of the threads are I have $200 to spend, so what is the best binocular for me.

Hello @Mono, @delia todd
Can this part of the thread be moved to a new thread, please? :unsure:
It is a very important debate but has nothing to do with glare.

Maybe beginning with the post #141 ?
I hope no one is against such movement. :cautious:

difficult topic...

I'll come out as a non-specific bird watcher, I see myself as a nature watcher, for me that includes moving and still nature, stars, animals in general but also birds, especially birds of prey, but also everything that is of interest, perhaps randomly but that too enjoyment.

According to this profile I would probably be out and would have to go to the astronomers who would throw me also out if the time came.

Even if there is a lot of nonsense written here, I would fear that the general transfer of knowledge would dwindle somewhat if you only accept people who deal exclusively with birding and how is that supposed to work? Should the new users first fill out a knowledge test about ornithology?

Let's get this thread back on topic. At this point in the thread, let's summarize what to look for in a binocular to avoid glare and list some of the binoculars members have found to be glare resistant and glare prone. We will add to this list as more glare resistant and glare prone binoculars are noted.

Glare resistant Binoculars


1) Most Zeiss FL's, especially the 8x56 and 10x56
2) Most Swarovski SLC's, especially the 8x56 and 10x56
3) Most 8x56's (Big EP)
4) Most Leica's (Well Baffled)
5) Most Zeiss SF's 42 mm, especially the 10x42 (SF 32 mm are not as glare resistant)
6) Fujinon HC 8x42
7) Opticron Aurora 8x42
8) Most EDG's especially the 7x42

9) Canon 10x42 IS-L
10) Swarovski Habicht 7x42
11) Meopta Meostar 7x42 SLC
12) Nikon EII 8x30
13) Swarovski Habicht 10x40
14) Leica Noctivid's
15) Most Zeiss Conquest HD's, especially the 8x56 and 10x56
16) Leica Trinovid HD 8x32

Glare Prone Binoculars

1) Nikon M7 8x30
2) Swarovski Habicht 8x30
3) Hawk Frontier EDX 8x32
4) Swarovski EL 8x32
5) Kowa 8x25 SVII
6) Swarovski NL's

7) Zeiss 10x42 HT
8) Nikon HG 8x30


Important things that control glare in Binoculars

1) Good Baffling (Leicas are known to be well baffled and blackened inside)
2) WA can be worse than narrower FOV binoculars because of the binocular design
3) Large EP aids glare control because it never reaches your eyes
4) Binocular design failures, especially reflective surfaces in the light path

Dennis this is a pretty good list imo. Im thinking that 8x32SF should be on the glare prone side. I had them out today with the EL , 8x32UV and 8x42 MHG. The EL was better than than SF, the little UV was the best.

Suggestion: include the Zeiss FL 10x56 in the first category. Their EP is significantly smaller than the 7mm of the 8x56 but the view thru them is glare free.
 
when I switch to my Swaro CL 8x30 after using my Trinovid HD 8x32 for some days I immediately notice the glare looking through the CL.

When you use a binocular for a while and go to another one, you immediately notice the differences. The CL 8x30 is not too bad for glare, but no doubt the Trinovid HD 8x32 is better. Leica's seem to be really well baffled. Thanks!

And often even Henry's has paled in comparison with yours... it must get so lonely...

I gather that the real aim here is to understand what makes some models more susceptible to glare than others:
1) Good Baffling (Leicas are known to be well baffled and blackened inside)
2) WA can be worse than narrower FOV binoculars because of the binocular design
3) Large EP aids glare control because it never reaches your eyes
4) Binocular design failures, especially reflective surfaces in the light path
#1 and 4 are essentially the same, and very well known. #3 has emerged recently as a good addition, if I recall correctly, thanks to Henry... though it really only helps birders who like 7x, given the desire for relatively compact bins. #2 seems dubious, since your list of good performers includes E II 8x30 with a very wide FOV, and the glare monsters include Habicht 8x30 which is quite narrow... can someone remind us why it has a glare problem?

As to those lists, it would be good to have careful side-by-side comparisons of glare in different models, rather than just anecodotal reports that this or that one is a glare monster, or not.

All I do to test for glare is use the binocular as the sun is setting and look right under the sun. You can separate a glare resistant binocular from a glare prone one pretty quickly. Do they show glare or not? I have tried that test with most of the binoculars on the lists, and I agree with most of the results.

Experienced users reports on which models are glare resistant and glare prone is very valuable and useful information because a lot of times we all see similar problems. The main purpose of this thread was to compile a list of glare resistant and glare prone binoculars so if you don't like glare, you would have a place to start in choosing your binocular.

It is not the intent of the thread to try to understand what causes glare, although we have talked about it in relation to what models are glare resistant and what models are glare prone. To try to single out all the different types of glare and what causes them and what binocular suffer from them would be impossibly complicated.

. . . It is not the intent of the thread to try to understand what causes glare . . .
. . . or seemingly to make even the most fundamental distinction between different types of glare.


Nine pages in, and anyone who’s battled on so far, would still have no real idea of the different afflictions
that the various 'Monsters' have - and importantly to what degree.

And so how is anyone helped in making an informed decision about a binocular that seems otherwise acceptable?


A primary distinction can be made between:
• veiling glare (an overall effect, where the whole image appears washed out);
• specular glare (a localised effect, where there are bright reflections in particular parts of the image), or;
• some combination of the two.
e.g. see: Lens flare - Wikipedia

The best for glare? Aurora 8x42. You have to be stupidly dangerous to induce it.

The worst for glare? NL Pure 8x42. What's worse is how utterly random it is, and how it spikes, not just veils. I hate it, absolutely hate it and wouldn't use an NL again. Ever.

I don't consider glare as much of a problem with the NL Pure as you do. Still, it's strange that such an imperfection exists with a top model like NL Pure. It's like one could wonder if the brands had an agreement not to totally outcompete each other, but always have some flaw, so all of them keep their fans.
