I can, however, see both my hands when they are aligned behind my ears and spaced about one foot out from the sides of my head. This is more than 180 and quite a silly act to perform in response to an email.
Either way, the point is that angle of view is not the determining factor, the size ratio is, one of many things in the universe I was unaware of.
If 50 is optimal, I wonder why Zeiss (or Kyocera) chose 45 for the G. Anyone know?
