Abstract
An auto-focus control camera includes an arrangement for measuring distance to a subject to be photographed, a calculator for calculating the degree of out of focus and an actuator for actuating a motor that shifts camera picture taking lens to a proper focus position according to the calculated result. The auto-focus control camera further includes a detector for detecting a time it takes for the arrangement of distance measuring and calculator to complete its operation. If the detected time is within a predetermined time period, the actuator is made operative to complete the photographing operation with auto-focusing, and if the detected time is longer than the predetermined time period, the photographing operation is carried out without auto-focusing.
