  • Patent number: 11947184
    Abstract: A lens barrel includes: a variable-power optical system including a focus lens group; a focus actuator configured to move the focus lens group supported by a support forward or backward in a direction of the optical axis to change a shooting distance; and a moving unit configured to, in response to receiving a driving force for changing a zoom magnification, move a position of the focus lens group in the direction of the optical axis to a position corresponding to the changed zoom magnification. The moving unit is configured to move the focus lens group in the direction of the optical axis by the driving force such that a change in a shooting distance due to a change in the zoom magnification is within a predetermined tolerance when the focus lens group is at a position corresponding to the minimum shooting distance, at every zoom magnification.
