Sorry if this should be in talk photo if it should move it please mods..

People on here always go on about how good this lens is and how sharp etc..
Well that got me thinking about how good a lens is the human eye is a camera lens..... and how you would classify it as part of a camera. I did some diggin about and found these stats.

your eye is the equivalent of a f2.1 - f11 lens with iso 1 - 800 with a 17mm focal length and 25fps..

kinda cool really especially when the brain acts as a 500 ish megapixel camera with HUGE storage capacity (for some)

has anyone heard any different or know any other cool stats???? or what lens would describe your eyes best...

mine would be a slightly manky east german type with bad optics but still usable with the right filters!!! :clap:
 
I wear monocles on both eyes to protect them. That's right, monocles. Not spectacles.
 
I wonder if it's possible to do an infra red conversion on the eye and brain.

saying that the uv filtered multi coated bits of glass i stick over my eyes every day cost £180... hell i would never pay that for a filter. plus my work ones are 30 quid cheapos
 
I rekon my eyes are better in low light than f/2.1 @ iso 800......

As a precision optic, I think the human eye is pretty poor as is the sensor behind it. The lens is a simple meniscus lens and the intermediate medium between the lens and sensor is full of all sorts of crud and the sensor has a separate lot of photosites for normal and low light vision, spread over a small area with a hole near the middle of it. What makes eyes seem to work so well is the extraordinary amount of correction applied by the software which reduces all the abberations and combines the twin images into what we actually see.
 
Don't forget the upside down and backwards image that actually falls upon our retinas...
 
And not to mention the dark "floaty" bits we get to see in our view of vision when we stare at a pale blank background. With that in mind, if the lens/sensor in my camera is anything like our eyes, I'd take the camera straight back to where I got it from and demand a replacement there and then!!
Oh, and our eyes is the equivalence of 35 mm, I think. No zoom function whatsoever. How boring is that, eh? :-D

Drifting away from the main point, I'd love the ability of having x-ray vision.
