ABSTRACT:
A lens barrel includes a telescopic cylinder, at least one movable lens, and a retractable lens. The telescopic cylinder includes at least one movable cylinder that can be accommodated in a fixed cylinder. The movable lens is retained in the movable cylinder. An optical axis of the movable lens determines a reference axis of the lens barrel. The retractable lens can be retracted in a plane perpendicular to the reference axis from a photographing position on the reference axis to a retracted position off the reference axis. In a photographing state, the retractable lens is adjacent to the movable lens, and the movable lens and the retractable lens are coaxially aligned along the reference axis. The retractable lens moves to the reference axis from the retracted position immediately after the movable cylinder of the movable lens reaches a maximum protruded position.
