ABSTRACT:
A microprocessor (CPU) controlled autofocus single-lens reflex camera having an interchangeable lens displays the subject distance (3) and the corresponding subject vertical and horizontal dimensions (1,2) in the camera viewfinder adjacent to the in-focus picture (4) which normally appears in the viewfinder by calculating data obtained by a subject distance detecting means and by a focal distance detecting means for detecting the lens focal distance which is used to determine the field angle. The relationship in size between the normal camera picture size and the subject (4) are calculated to provide the corresponding subject dimensions which are displayed in the viewfinder (1,2,3).
