ABSTRACT:
A zoom camera includes a lens that is movable from a housed position to an arbitrary position in a photographing enabling range. A lens driver drives the lens, a lens barrier moves between opened and closed positions, and lens barrier closing mechanism moves the lens barrier between an opened position and the closed position. A detector detects that the lens has moved from a position within the photography enabling range to the housed position and controller prevents the lens barrier closing mechanism from moving the lens barrier to the closed position unless the lens is at the housed position.
