PROBLEM TO BE SOLVED: To provide a lens barrel capable of reducing power consumption.SOLUTION: The lens barrel includes lens frames 310 and 320 for holding a third lens group L3 and a holding frame 330 that holds the lens frames 310 and 320 so that the lens frames can move in a plane perpendicular to an optical axis. Of the holding frame 330 and the lens frames 310 and 320, at least the holding frame 330 is provided with an energizing means for generating a force for lifting the lens frames 310 and 320 in a direction against gravity. |
