An automatic follow-up device for a camera is arranged to automatically capture a heat source, such as a human being, within a photographing field on the notion that a moving object to be photographed is often a human being; and to automatically adjust the magnification of a photo-taking optical system in such a way as to adjust the size of the image of the object to have a given portion of an image plane allocated to the object irrespective of the distance to the object.
