Re: Binocular Conundrum: Field of View?
"FoV and apparent FoV are angular measurements and FoV at 1000 meters is a distance."
Those are two different ways to say the same thing. The angular measurement will always translate into the same FOV at the same distance, 1000 yards or otherwise.
Anyone who would try to convince you otherwise, is either a charlatan or failed high school geometry. Included angle, distance, all basic fixed numbers and this is how we get cosines and tangents and all those other painful numbers that used to come from a book of tables before pocket calculators replaced slide rules. A 3-4-5 triangle will always be a 30-60-90 degree triangle. Same same.
And whether it is the field stop or the exit pupil, as long as the image is being cropped the same way at the same point, those will be the same as well, all else being equal.
