The term "Nagler-like" generally means a WIDE AFOV in additon to edge sharpness. Most OEMs consider their binos to be WIDE if the AFOV > 65°. So I am suprised no one has mention the Nikon 8x30 E2 with its 70° AFOV (8.8° TFOV). Generally still available in most of the world ex USA for some silly reason.

I have data on over 60 different binoculars in my database. A wide variety from 7x35 to 25x100, and many many small sizes and large sizes in between.

Less than 10 binoculars have Afov of 65°. I would say a 65°+ Afov is quite uncommon in binoculars. Only 4 of them handle the wide field well, so less than 7% of 60 binoculars have a GOOD wide field 65° or larger.

There are just as many in the data that have 50° or less as there are that are 65° or greater.

Half of all binoculars range from 60° to 65°

More than 20 binoculars have Afov of 53° or less. We sometimes hear people describe this as tunnel like, yet more than 1/3 of binoculars have eyepieces with these narrow field stops. Only 3 of these handle outer Afov sharpness poorly.

More than 15 binoculars have Afov of 64° or greater. Of these, 10 handle outer Afov sharpness poorly.
