Hi,
Decided to upgrade binoculars. Ordered pair of NOS Japan made Razor HD 10x42. Meanwhile stumbled upon a NOS Japan made Viper 8x42. Bought both figuring they'd be different enough.
Finally had both side by side and was surprised to find the have an almost exact FOV.
10x Razors 362' at 1000' 6.9°
8x Vipers 347' at 1000' 6.6°
So I'm confused. I'm looking at a circle that is 10x closer and it 362' diameter and one that is 8x closer 347' diameter...
Usually as power increases FOV gets smaller all things being equal.
Here is actually seems like the 8x are reaching farther...
Confused in AZ....
Thanks!
