Human eye lens
If a human eye was a lens what kind would it be. I did some research about this. So I find on the net that an average human eye would have:
from 17 to 24mm
Minimal focus distance 7cm-infinity
I find it interesting to know these. If you know more precise data please say it.
And one more thing, our autofocus system focuses in 350ms.
