Two questions:
it seems like there is more "focus range" when I'm view something at 50 yards versus a much shorter amount of knob range when viewing something at 500 yards. Is there a specific reason in physics for this or am I just imagining it?
I have a 3x9x36mm rifle scope - is the exit pupil 12-4 or doesn't that apply to rifle scopes? Thanks.
