Abstract
A camera having an auto zoom function includes: a taking lens for photographing an object; a distance measuring device for measuring a distance to the object; a magnification setting device for setting a photographing magnification for the object; and a focal length calculator for calculating a focal length of the taking lens to obtain the photographing magnification set with respect to the distance to the object. Auto zoom operation is carried out by automatic movement of the taking lens so that the focal length of the taking lens may be equal to the calculated focal length.
