Aside from the Swift 804, 820 etc. series of bins are there other manufacturers using the ED glass in there PORRO binoculars ?
I am not aware of any current production fitting that, other than the Swift you mention.
There may be an individual focus model or two for the astronomy market . I also am not up on the specs for the giant 100mm to 150mm astronomy binoculars.
I have never seen one for sale used, but years ago, Celestron made a handheld porro that was "ED", i think it was 9.5x44 or so. I do not think it had very close focus.
I have the SwiftAudubon 8.5x44 ED. Have had it 8-10 years. I consider it truly apochromatic. Zero CA under any lighting conditions, across its field.
Promaster has a Porro binoculars that has ad copy saying it. has ED glass. I am not certain about it Sometimes some of these new companies make a good description for the roof model and then they repeat it for other models they also sell.
They want 400 dollars. It is pricey. It is a hard swallow to pay for a trial.
