Re: Binocular Conundrum: Field of View?

"simpleist the higher the magnification {first #) the narrower the field of view."

As a sweeping generality, yes. Now take a Nikon Monarch 5 10x42 and a Nikon Monarch 7 10x42, both with 4.2mm exit pupils, both 10x with a 42mm objective lens. The FOV for the M7 is stated as fully 50% wider than it is for the M5.

Perhaps the magnification for one of them has been grossly mis-stated? No, there's something else "wrong" here. (Not to pick on Nikon, it isn't just them.)
