Here is a link to the information that I found interesting: Linky-Linky In a nutshell, this is what I gleaned from the article: Our eyes are equivalent to 324 mega pixels, an ISO rating of 1-800, 10,000:1 dynamic range, a 22mm focal length, and an aperture of f/3.5. There are various other specs from other authors. There may be different interpretations of what I read on this page. I am not stating anything absolute. I was just curious and decided to do some research. This page seemed to make the most sense out of the ones I read.
