It will depend on your age.Hello , please post your answers.
Thanks
Denco, because 3% difference is not obvious. Will 8x56 meopta will be a lot brighter than EL 8.5x42 because of 55% more light entering into the binocular? Will the difference be noticeable only when my eyes are dilated more than 5mm ?Henry Link.
"I don't think transmission differences of less than about 3% are detectable by eye. At least that's my threshold in a very careful direct comparison between two optical devices. 5% is relatively easy to detect in a direct comparison and 10% is very obvious. I'm reasonably certain that fractions of 1% are invisible. There is probably a 1-3% sample variation in different specimens of the same model binocular. Since light transmission curves in optics are never straight lines we often detect differences in the transmission curves of two devices as color differences rather than brightness differences."
are saying that from experience with Meopta and Swaro or just guessing? i can get Meopta 8x56 for $850 vs SLC 8x56 for $1950. I already own 8.5x42 EL. So I am trying to decide.It will depend on your age.
If you are younger than 60, the Meopta will win handsdown.

Thanks Dale. Good to hear from you.A few years ago, we did a little (non-scientific) experiment playing around with transmission and who could detect what. We integrated colour-neutral grey filters directly in to the binoculars and - if my memory serves me correct - it turned out that during the day, (almost) none of us could tell which binoculars had a 5% reduction filter, but most could tell which was the "duller" binocular with 7% and 10% filters. A few more could pick the -5% at dusk.
Colour effects (varying transmission curves) were, however, super obvious. Even slight changes in the colour fidelity were immediately obvious and had us wildly guessing which binocular had the higher transmission. Two binoculars with the same standard transmission value but differing in their "warmness" or "coolness" had people perceiving the one or other binocular to be significantly brighter than the other.
If those transmission values are accurate, one with good eyesight would notice 5% difference in transmission. At 2% difference in transmission in the same aperture and magnification, I doubt many observers could notice the difference.

First of all, you asked for the difference in dusk use in a 42 versus 56mm and now you are talking about 56 versus 56. Considering your age, you can't compare a 42 with a 56 during dusk and dawn use (under the condition of almost the same quality).are saying that from experience with Meopta and Swaro or just guessing? i can get Meopta 8x56 for $850 vs SLC 8x56 for $1950. I already own 8.5x42 EL. So I am trying to decide.
There you go with all that LOGIC stuff, again!First of all, you asked for the difference in dusk use in a 42 versus 56mm and now you are talking about 56 versus 56. Considering your age, you can't compare a 42 with a 56 during dusk and dawn use (under the condition of almost the same quality).
To bring it subtle, I have them all.
If you want the best of the best in this area (56mm) I would go for the Zeiss HT54 or the SLC56.
The Meopta 56 is value for money and nearly as good as the other two........ but not as good.
It's quite simple, top quality spoils you and once you've gotten used to it...........
And don't rule out the after sales period. Swaro's customer support is top notch.

I was speaking of two 8X56 binos, not 8.5X42 and 8X56.All true, but the OP asked about dark hours and then, given his young age, it is the exit pupil that counts. The 8x56 will be twice as bright, give or take the few % difference in transmission. This assumes an eye pupil size of at least 7 mm in the dark.

Subject came up in the past....are saying that from experience with Meopta and Swaro or just guessing? i can get Meopta 8x56 for $850 vs SLC 8x56 for $1950. I already own 8.5x42 EL. So I am trying to decide.

In my experience an 8x56 will almost always be brighter than an 8.5x42. In bright sunlight you might not notice much difference between the two but even in the daytime you sometimes look into shaded areas or you are under canopy and the 56 mm will be brighter. In low light situations and at dawn and dusk there is no competition between the two. The big 56 mm will kill the 42 mm. That is a big reason I have like 50 mm and above apertures and also for the easier eye placement with the bigger exit pupil.
I had both the Meopta Meostar B1 8x56 and the SLC 8x56 and the Meopta is just as good for less money. Here is a comparison of the Meopta Meostar B1 15x56 and the Swarovski SLC 15x56.are saying that from experience with Meopta and Swaro or just guessing? i can get Meopta 8x56 for $850 vs SLC 8x56 for $1950.
