Re: ED glass in binoculars

I could look at a crow against a bleak, winter's sky with the 10x ED bin and not see any color fringing on axis and even a bit off axis. ....Turn those ED bins on a Yellow Finch or a Cedar Waxwing or on colorful bed of flowers and be prepared for a "Wow" moment.




I would have to agree with that from my limited experience with ED binos.
I have the Swift Audubon 8.5x44 in three flavors, regular, (older non-armoured), ED, and roof.

The above quoted text is true, for me. Of course, as EDZ pointed out, other factors may be at play between ED/non-ED models, even from same manufacturer/brand. Also, there can be variation within copies of the same model...

But i should add, that regarding my three binos mentioned above, the ED difference is very clear (for me, your mileage may vary) when looking at for example the rim of the moon, also.
