ABSTRACT:
The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor.
The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.
