Abstract
A camera, equipped with a viewfinder having an optical axis different from the optical axis of the photographic lens system, has a parallax compensation apparatus for compensating for the parallax between the viewfinder and the photographic lens system. The parallax compensation apparatus includes a distance measuring device which measures an object's distance from the camera and an optical axis moving device which moves the optical axis of the photographic lens system according to the parallax, which is based on the results received from the distance measuring device, thereby matching the photographic image plane with the viewfinder field. In addition, the optical axis moving device moves the optical axis of the photographic lens system to compensate for hand trembling or other motion of the camera during shooting.
