No idea honestly, but I have used several different lenses (5 lenses, 4 cameras)
and all of them produce the same answer.
#1 Philips ToUCam w/ two different lenses.
A) Cannon C-mount 16-100 zoom lens
B) A single dual convex lens with a 35mm focal length
#2 Sony HandyCam (video tape recorder)
#3 Sony DSC-F707 (5MP digital still camera)
#4 An unknown and Ancient VHS camera
Of all the cameras above, I did run some tests on the webcam with the DCX lens,
here are some pictures:

BTW, the Human Eyeball is a terrible lens / detector system, and an eye at the
knife edge is industry standard for several well known companies.
