摘要
A camera having selectable normal and trimming photographing modes and a photographing zoom lens, has a control system, including a zooming motor for driving the zoom lens, operable to set a desired focal length in response to the actuation of a control element. When a desired focal length is within the normal zooming range of the zoom lens, the normal photographing mode is selected and the zoom lens is driven to the desired focal length in response to actuation of the control element. When the desired focal length is greater than the focal length at the telephoto end of the zoom lens, the trimming photographing mode is selected, and the zoom lens is driven to the telephoto end, is then driven toward the wide angle end to a predetermined focal length at which a product of the predetermined focal length and a predetermined trimming magnification is equal to the focal length at the telephoto end, and is then again driven toward the telephoto end to a further focal length at which the product of the further focal length and the predetermined trimming magnification is equal to the desired focal length.
