Just for fun…without looking up or checking anywhere on the internet, what do you think the average focal length of typical human vision is? Add your comments to guess! Ill post some interesting specs on human vision later.
Here they are:
Notes on the Human Eye:
Equivalent Lens Focal Length: ~22mm
Aperture Range: f 2.1 – 8.3
Equivalent Mega Pixels: ~576MP
Dynamic Range- 10,000 range in contrast detection
ISO Range is changed by amounts of Rhodopsin levels

Wiki Article on Apertures
Think how wide the field of view is, I would guess 2 to 5mm… I will have some vignetting and barrel distortion after some Guiness tonight.. Happy St Pattys day all!
Id say 35mm?
I got to use my first 17-24mm lens last week and with it seemed close to what I saw with my naked eye. I would have to say 15 to 17mm?
I think it is 50mm lens with a full size frame camera. Am I right????
My guess is 17mm.
22 MM !!
I’ve always heard that a 50mm lens (on a full frame camera body) is what the eye sees.
Sorry to go off-topic, but your entry today made me think of this: http://www.stumbleupon.com/su/1NPMqx/www.inhabitat.com/2010/03/17/solar-powered-augmented-contact-lenses-cover-your-eye-with-100s-of-leds//r:f
