I see this written all over the place but really have no idea what it means. My field of vision is way wider than a 50mm lens affords (yes, I did go down to 33 on my DX). Of course, most of my FoV is out of focus at any given time. And the magnification of a lens at 70mm is about the same size as I see things through my eyes. (At least with objects at a distance: I haven`t tested close-up ones). So what`s with 50mm being called "normal"?
