Whoa - something is seriously wonky in that article. He says the human eye has a 160 degree field of view, which is fine, but translated to camera focal length that's something like a 12mm lens that results in pictures like this.

I don't know enough about optics to resolve the issue (badum ching), but I think there's some confusion about focal length, field of view, and lens distortion going on here.

edit: Ok, in the comments for that article he does clarify the difference between field of view and perspective. It sounds like indeed a 50mm lens results in similar perspective to the human eye - which is what is going on in these pictures of the model - and the field of view as discussed in the article is a totally different topic.
