Abstract
A parallax compensation system and method is provided for a camera including an independent viewfinder. For close focus pictures, the camera's taking lens is shifted towards the viewfinder. In one embodiment, for far focus pictures the camera's taking lens is moved away from the viewfinder and is not centered on the image recording medium axis. The lens shifting is accomplished by mounting the taking lens eccentrically in a lens barrel. Rotation of the lens barrel shifts the taking lens towards the independent viewfinder for close focus shots. In one embodiment, the viewfinder axis is tilted towards the taking lens to help eliminate parallax in close focus pictures.
