comparing big objective bins... (1 Viewer)

Looks like the most CA I was ever going to find with these was in strong light peering into the corners at high contrast things like the edges of white walls or shiny things. Even then I couldn't induce much if any.
Currently viewing tree silhouettes against a grey background and nothing, nowhere I search for CA can I find any on this dreary day.
The Fujinon is excellent at controlling CA.
Regarding the OP's questions I can't knowingly comment on the Zeiss but I think the only thing it could offer which may likely be seen as advantage over the Fujinon is CF. I don't imagine it would best the Fujinon in any meaningful optical way. The Fujinon is an optically excellent binocular.
I've enjoyed mucking around trying to fault them and hopefully it's of some value to the reader. It's been a good reminder of how good these really are, hadn't picked them up for a while.

Slingworks. Why don't you get a Swarovski SV 10x50 or SLC 10x50? They have a big enough aperture to satisfy your aperture fever and I think you would prefer either one over the Zeiss 8x56 FL or Fujinon FMTR 7x50. Either one would also be a better all around lighter and more versatile binocular. The majority of the time a 7mm exit pupil is not going to be needed for birding and unless you are younger your pupils will probably not open wide enough to benefit from a 7mm exit pupil. Due to the Twilight Factor you will see more detail in low light with a 10x50 than you will with either the 7x50 Fujinon or the 8x56 Zeiss and they will look just as bright to you. Try a 10x50 versus a 7x50 sometime in low light.

Thanks for the replies.

Denco when I shop for glass cost is a big part of my calculation. In this case I have some like new Zeiss lined up for 1k. Fujinons seem to hover around 5-600 used? The SLC sounds like a good option. I don't think I've handled any to try out.

I like the Swarovski Els really well but they're VERY expensive. I can't say I've ever seen a pair for sale under $1300 or so?

Peter I happened to come across these on Ebay, what do you think?
No I'm not shopping for this glass, I just came across these and found them very interesting:

Personally I’d avoid. Modern Astro bins will have better optics and allow you to use commercial Astro eyepieces, many of which have very good performance. Then you can change the magnification at will, depending what you’re looking at. (AStronomers like looking at the edges of the field!) 30x for general 60x for moon, 18x for widefield viewing all with the same system. Chinese glass has got very good of late, APM and Oberwerk being examples.
Another warning is that there aren’t many posts on CloudyNights binocular group where the Astro binocular experts lurk. Rather too many “rare” adverts out there.

PS googling, Binomania has a review (need a translation), http://www.binomania.it/binocoli/zomz30x90/zomz30x90.php Not too bad overall, though some areas it is not the best
A modern equivalent with ED glass would be this for little more cost (more common and more reviews about), https://oberwerk.com/product/oberwerk-bt-82xl-ed-binocular-telescope/
Or something like the APM 25x100ED http://apm-telescopes-englisch.shopgate.com/item/333632303931

I guess my point is a 10x50 would be a better all around binocular for birding rather than an 8x56 or a 7x50. It doesn't necessarily have to be an EL if that is out of your price range. I would definitely stay away from IF focuser's for birding as in the Fujinon. The Fujinon IMO is more for astronomical use. An 8x56 is going to be a tank to hold for any length of time when observing birds unless it is on a tripod or monopod. Are you getting these for birding or just low light observing from a static position? Here are some nice Leica Ultravid's in 10x50 on Ebay.

Thanks slingworks for detailing the ZOMZ 30x90.
This is one that I have not come across before.
I wouldn't pay that much for this binocular.
It seems to be made of parts from other binoculars with larger front barrels.

There is the Kronos 26x70, which I know but haven't owned, although I have had numerous 20x60s.

I have a 25x100, probably Chinese, but don't use it. Too heavy.
I prefer large telescopes to big binoculars.

B.
