[QUOTE="Chosun Juan, post: 3150226, member: 92780"] David, That was the point. The FOV (or brightness for that matter) does not change, just the part that appears sharp to the eye + bin system which may then 'appear' brighter as a psychological illusion. There's just something about the opacity of the blurry part of the field that seems duller than particularly the transparent central view of a good porro. (Swift Audubon 8.5×44 ED is a good case in point) :t: Chosun :gh: [/QUOTE]
