A method of operating a camera in which either of a normal photographing mode and a trimming photographing mode is selectable, the camera having a zoom lens with a range of focal lengths between a telephoto end and a wide angle end, said method comprising:
- selecting a desired focal length;
- and
- when the desired focal length is within said range, selecting the normal photographing mode and driving the zoom lens to the desired focal length,
- when the desired focal length is greater than the focal length at the telephoto end, selecting the trimming photographing mode, driving the zoom lens to the telephoto end, then driving the zoom lens 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 then again driving the zoom lens 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.
