Abstract
A lens barrel includes a rear movable member holding a rear optical element, an off-axis removable member holding a removable optical element, a front movable member supporting the off-axis removable member, and a removal driving member supported by the front movable member. When the front and rear movable members are at the photographing positions, the removable optical element is positioned in front of the rear optical element, and when the front and rear movable members are at the retracted accommodating positions, the removable optical element overlaps the rear optical element. When the front and rear movable members relatively move rearward, the removal driving member contacts the rear movable member to be slidable in a driven direction of the off-axis removable member while the off-axis removable member does not contact the rear movable member.
