Re: Binocular Conundrum: Field of View?
I kinda skipped the last few posts so, I don't know if this was mentioned or asked but look at it as though it was a zoom lens, same glass both ends but the difference in length between both ends determines the FOV; shorten the lens the wider the FOV, extend the lens the narrower the FOV, same optics but different effect so, the question is, are the dimension on both binoc barrels the same. I know it takes very little movement on one of my lenses to change the FOV
Another thought, all things being the same, maybe the objective lens has a more pronounced fisheye cut to it, giving it a wide FOV
