    This is just my theory, feel free to contradict it.
    Depends on how wide apart your eyes are. Really - ever notice W's eyes are close-set as a rattler's? Makes him think Iraq is next door.

    First, as I and others have stated, the field of view of the human eye is far greater than that of a 40mm lens on a 35mm camera. Of course, that's not the whole story.

    Second, from the same position, the perspective will remain the same no matter what focal length lens you use. (Of course, a fisheye lens will distort things, but that's another issue.) That is, you'll get the same size relationships from a full-frame photo taken with a 135mm lens as you'd get from an appropriately cropped photo taken with a 35mm lens. Likewise when changing formats (35mm to medium format, say). The size relationships change only when we shift position (or use weird lenses, like fisheyes or shift lenses).

    The premise of the question -- that there's a best match between a lens focal length and what humans see -- is simply invalid. The human eye, the human visual cortex, and higher-level human perceptual systems are simply too different from those of a camera and film to make the comparison meaningful. See my rather lengthy earlier post for why.

    Considering that throughout history the normal (i.e. average) human perspective on things has been defined by poverty and the attempt to overcome it, I would say that the equivalent lens to the human perspective would be the lens you cannot afford and do not buy...

    I would say that the AVERAGE human perspective is not about personal self interest but about the good of the tribe, group, and/or family. If not we probably, as a species, would not have survived.

    The human predators and the parasites are the exception.

    If we are looking for the lens for the AVERAGE perspective then naturally we would have a 50mm. Cheapest, most practical and least creative.

    I couldn't think of anything witty to say so I left this blank.

    Social psychology is clearly not the object of this thread as evinced by the truly uninformed, impressionistic opinions espoused. Why not stick to the subject of physical psychology, visual perception?

    Then what we need is a lens that approximates a normal lens, but has an angle of view of a fish eye. It would need to be able to focus like a macro or micro and in doing this become a very short lens or telescope to emulate an extremely long lens, and, of course, everything in between. That lens doesn't exist.

    I'm thinking the comparison can be viewed as pointless if kept to the physical and becomes interesting when...


    Oh never mind.

    I'd like to find a "Beer Goggle" lens that sees the world from the perspective a guy who is sitting in a bar at 2:00 in the morning after a full night of drinking copious amounts of beer. Every woman looks like a super-model.
    That is called grain. It is supposed to be there.

    I had one of those lenses, but the camera must have been loaded with Coyote Ugly film.
