Abstract
A lens barrel includes a plurality of lens groups including a retractable lens group, a plurality of lens retaining frames to respectively retain the plurality of lens groups, a movable lens barrel to retain the plurality of lens retaining frames therein, and a lens retaining frame driving device to drive the lens retaining frames via the movable lens barrel. The lens retaining frames, the movable lens barrel and the lens retaining frame driving device move the plurality of lens groups between a collapsed state and a photographing state. The retractable lens retaining frame is movable between a position on a photographing axis and a position inside a housing located outside an inside diameter position of the movable lens barrel in the collapsed state by moving in a direction inclined relative to the photographing axis and moving in a direction orthogonal to the photographing axis.
