I'm up high seat waiting for some Fallow and fiddling with my optics like you do.
The question I have is what determines field of view ? My Binos at 8.5 X 50 have the same field of view as my scope when the magnification on scope is reduced to X 5. When set at 8.5 it is much narrower FOV than the Binos.
Any explanations gratefully received .
