Claim:
1. A lens barrel comprising: a base barrel; a first guide portion held by the base barrel; a movable barrel protrudable and retractable with respect to the base barrel in an optical axis direction; a second guide portion held by the movable barrel such that when the movable barrel is protruded with respect to the base barrel during transition from a retracted state to an image capturing standby state, the second guide portion protrudes in an object side with respect to the first guide portion; a lens holding member including a first held portion and a second held portion, the first held portion being held by the first guide portion so as to be movable in the optical axis direction, the second held portion being held by the second guide portion so as to be movable in the optical axis direction; a lock portion for setting a positional relationship between the first and second guide portions during the transition from the retracted state to the image capturing standby state so that after the lock portion sets the positional relationship between the first and second guide portions, the lens holding member is movable in the optical direction in an image capturable state while maintaining the positional relationship between the first and second guide portions set by the lock portion; an initial position detector for detecting an initial position of the lens holding member in the optical axis direction; and a controller for controlling movements of the movable barrel and the lens holding member so that a movement of the lens holding member toward the initial position detector is started during the transition from the retracted state to the image capturing standby state before start of setting of the positional relationship by the lock portion.
