Why is a focal length of 50mm considered a standard? I've been
reading that 50mm is very close to what the human eye see's.
I'm wondering which human is that? when I measure my perphial
viewing angle it's slightly greater than 90 degrees.

which according to this nifty little .swf applet:

http://www.usa.canon.com/eflenses/lens101/focallength

is somewhere between 20mm and 28mm...(i'd estimate 24mm). 

Am I gifted?
