Obviously there's an inverse relationship between FOV and magnification, but why isn't it exactly inverse? Top quality 10x binos offer FOV from 330 (typically) to 360 ft, from which one would predict 412 to 450 ft at 8x, 470 to 514 ft at 7x. But in fact few 8x binos exceed 400, and 450 is exceptional at 7x. If you want to sacrifice magnification for FOV, why do you get cheated?
