Here is a trivial about our human eye taken out from Introduction to resolution and MTF curves by Norman Koren. Don't ask me why I was reading this.
Focal length of our eye (nominal) is 16.5 mm with f-stop from f/8 (pupil size 2mm for bright light) to f/2.8 (pupil size 5.8mm for dim lighting)
Anyone can tell me what is the ISO equivalent of our retina?
