摘要：
A lens barrel is capable of selectively establishing a power focus mode in which an internally housed motor moves a taking lens to a position of any desired focal length, a single "auto-focus" mode in which the taking lens is moved to a position which is in focus to a stationary object being photographed, and a sequence "auto-focus" mode in which the taking lens is continuously moved in focus to a moving object being photographed. Any one of these modes is suitably selected by a mode changing switch. A movement of the taking lens in each mode is initiated by an operating member.
