Abstract

A lens barrel and an imaging device which can be miniaturized, the lens barrel with a movable cylinder that moves along the optical axis with a change in focal length; first and second drive units in the movable cylinder; and first and second lens driven by the first and second drive units respectively to move along the optical axis relative to the movable cylinder. The movement amount of the first lens relative to the cylinder when the focal length is changed to a second focal length from a first state where the first lens is at a position closest to a subject with a first focal length is less than the movement amount of the first lens relative to the cylinder when the focal length is changed to the second focal length from a second state where the first lens is closer to an image plane than the first state.
