The human eye can focus on different distances without ever changing the perspective. Why is the change of focal length in a camera, on the other hand, always linked to a change in perspective? Is the behavior of the flexible eye-lens impossible to imitate with an array of lenses?
Edit: I'm talking about cameras going from a wide-angle to tele-photo perspective when going from short to long focal lengths because it also zooms in. The human-eye can also go from short to long focal lengths but doesn't exhibit a change in perspective. Why are the two always linked in a camera?
