Re: Binocular Conundrum: Field of View?
Yes, same exit pupil diameter = same size image on your retina. What information that image contains is a function of the field of view. Larger FOV, you see more of the world. Smaller FOV, you see less of the world, but the cone of light on your eye is the same size.
It doesn't get any simplier than the formual provided. True FOV a direct function of field stop diameter in your case of otherwise identical binoculars.
