ABSTRACT:
In a camera using a zoom lens for effecting zoom photographing at a predetermined photographing magnification, a detecting apparatus detects distance to an object moving along the optic axis of the zoom lens and detects speed of the object. A control device causes the detecting device to detect the distance to the object and the speed of the object repetitively as long as an operation signal (e.g., a signal from a shutter release button) is produced, repetitively predicts the distance to the object after a predetermined time on the basis of the detected distance and the detected speed, repetitively determines a desired zoom position of the zoom lens on the basis of the predicted distance, and operates a driving device to drive the zoom lens to a desired zoom position.
