Abstract
A camera has an electrically zoomable lens with two modes. In the first mode, the zooming is continued during the continuation of a manual operation. In the second mode, the zooming is conducted to a focal length corresponding to stored information, which corresponds to a focal length arbitrarily selected in the zooming of the first mode. The stored information is retained even when the second mode is released, and the zooming to the focal length corresponding to the stored information is possble when the second mode is set again.
