Abstract
A lens barrel includes a support ring movable in an optical axis direction; a displaceable optical element supported by the support ring movable between a photographing position and a radially-displaced position in which the displaceable optical element is eccentrically displaced from the optical axis; and an advancing/retracting optical element supported by the support ring. When the lens barrel is in a ready-to-photograph state, the displaceable optical element is held at the photographing position, and the displaceable optical element and the advancing/retracting optical element are aligned in the optical axis direction. When the lens barrel moves from the ready-to-photograph state to an accommodated state, the displaceable optical element is held at the radially-displaced position, and the displaceable optical element and the advancing/retracting optical element are relatively moved so as to at least partially coincide with each other in a direction orthogonal to the optical axis.
