Abstract

A zoom lens camera includes a whole unit moving device to move a front lens group and a rear lens group together as a whole in an optical axis direction, and a relative moving means to vary a distance between the front lens group and the rear lens group. The whole unit moving means is driven during a zooming operation, and at least the whole unit moving means or the relative moving means is driven during a focusing operation to focus on a subject to be photographed.
