Light transmission is 90% in all EL and and the 10x50 by a whisker brighter ,which is more apparent in low light . I went for the swaro only for its size /flat field and use it for travel,nature,astro ,But you can't go wrong with the zeiss .of course nothing like having both .

I am seriously hesitant to see through 12x50 SV as I fear I will be tempted to own both FL and SV

Umasuthan,

Be patient. I recently bought (prior to deciding to also get the 12x50 Swaros) a Zeiss 10x56 Night Owl binocular. This is model was made in the late 1990's and was the last binocular type that Zeiss made which still used lead glass (which they spent 100 years perfecting) and it enjoys an excellent reputation for superb performance. That binocular hasn't arrived yet but it should in a week or so.

In any event, next August or September I'll be taking both that binocular and my new Swaro 12x50s with me to one of my multi-night high elevation/very dark sky observing sites and I will have an opportunity to compare both binoculars using them both in hand hold-able and mounted modes.

The place I go to observe is in the Southeaster Corner of Oregon State in the US and the region has lots of great scenery as well so I'll also be able to try the binoculars out on terrestrial targets as well.

So late next Summer I will write up my impressions of the two binoculars and post them here the Cloudy Night site.

Hey John,

I never thought about the exit pupil difference between 10x56 FL and 12x50 SV. Thanks for pointing. Looking forward to read your report

Also a larger exit pupil may not always be an advantage as depends on age and individual.
Above 40 the iris max dia may only be up to 5mm.
A higher magnification,Smaller exit pupil,so better contrast .
any way the dark sky report will be interesting.and as John said each will have its strong points depending on application.

Hi John,

I agree with you. All I did was compare the 12x50 Swaro vs 10x56 FL, and that is how they compare to me. During daylight, the FL was the brighter bino, indicating better transmission. Under the stars, the 12x helps the EL a lot to see more detail. It's lighter weight and better balance help in hand-holding. I find the 10x56 FL to (front) heavy for prolonged hand-held observing. They have no solid tripod support like the Swaro SLC's or the Nikon 18x70. Since I already have the incredible Nikon 18x70 tripod mounted, I decided not to buy the FL 10x56.

Instead I bought the FL 10x32. The sharpest 10x I have used with a beautiful very wide and quite sharp AFOV. Nagler-in-an-APO like feeling. Bright? No. Tiny? You bet!

Enter the FL 7x42. Bright? Yes! Wide true field? Yes! Lightweight and well balanced too. A great pair with the 10x32 for handheld observing for me. My eyes plague me with increasingly imperfect stars with exitpupils bigger than 3mm due to astigmatism. But I don't like observing with glasses, so this is my solution for that. Sharp stars? 10x32. Wide and bright? 7x42. And it has such an easy view. So last week I got those 2 FL's and really enjoy them.

On a tripod, there is nothing quite like the Nikon 18x70. I even prefer it to my Tak FS102 on low power deep-sky. Gorgeous views.

Umasuthan,
You asked about the transmissions of 10x56 FL and the 12x50 SV. Allbinos has measured this for the 8x56 FL and the 8.5x42 SV, and I suppose the coatings are the same throughout the series. Look down at the bottom of the reviews for the transmission plots.

FL transmission

SV transmission

The FL is significantly brighter over the most luminous daytime band and also at the scotopic peak around 510 nm. The SV profile is flatter however, and a couple of percent above the FL in the deepest blue.

Are there any non-Swarovision version of 12x50 EL binos from Swarovski?

There were no 50mm original model ELs.

No!

Incidentally, after using my Swaro 12x50s for a week or so (both terrestrially and astronomically) I decided to return the pair I ordered for a refund (they came with a 30-day return policy).

Optically, they're superb and the best 12x50 I've ever looked through. However, I found that while they're better designed ergonomically and easier to hand hold (reasonably steady for a 12x50) they still start shaking fairly quickly (if I'm hand holding them) after I place them on the object I wish to look at.

So given their high cost and the fact that I already have a pair of Zeiss 15x60 B/GATs (which are like the Swaro 12x50's bigger brothers) that I can use on a mount, I concluded that the Swaro 12x50s just didn't do enough for me to warrant keeping them.

This recent experience kind of takes me back to an opinion that I formed many years ago in relation to 12x50s and that was yeah, you can hand hold them some but to get the real value out of them you need to use the with a mount. And, once you decide to cross that threshold, then why not get a pair of 12x50s when you can get a nice pair of 15x56s, 15x60s, 16x70s or 18x70s instead?

In any case, it looks like I won't be getting to do a comparison of the Zeiss 10x56 Night Owls vs the 12x50 ELs. However, from past experience using many other different pairs of binoculars I can pretty much imagine what the likely outcome of such a comparison would be.

For some deep sky objects and Milky Way star fields the larger aperture and larger true field of the Zeiss 10x56 would provide the nicer view. But for many other objects and some portions of the Milky Way, the tack-sharp-to-the-edge 12x50s and with their higher magnification and greater contrast would produce the more engaging view. But with the 12x50s you really need to use them with mount to be able to get the type of performance out of them which they are capable of providing.

As for the Zeiss 10 x 56 FL vs the Swaro 10x50 ELs I'd say stick with the 10x56's provided you're pleased with the views that they're already providing you with and if you can hand hold them reasonably steady. You also have the option of getting a mount to use with them (at least some of the time) and I would recommend that. Else if you're not all that pleased with the views they're providing or if you find them rather difficult to hand hold reasonably steady then swithing to (but not supplementing them with) the 10x50 ELs might then make sense). Another good option is the 10x50 Fujinons but they're kind of heavy.

There is no single binocular that is best for all applications. What I think makes the most sense is to get a pair that is going to be very good for hand holdable use (e.g., an 8x42, 8x50 or 10x50) and also and second higher power and larger aperture pair (like the sizes I mentioned above) and use that with a mount. And then after you got those (which I consider to be essential requirements) adding a pair like the 10x70 Fujinons or Nikons makes sense for the very bright views of the Milky Way they can provide. But in order to get the most out of a fine pair of 10x70s you need (1) a mount and (2) be able to get to really dark sky sites to be able to use them at. In an urban or suburban location they're just not going to be able to perform up to their potential and therefore I would not recommend getting a pair if you can't take them to really dark sky sites to use them at.

John,

Thanks so much for the advice. That is very useful. I think you summed it up by saying "There is no single binocular that is best for all applications."

I finally managed to get my hands on 10x56 FL and 12x50 SV. Will try them both and share my experience.

I have posted my experience with EL and FL in a separate thread.
