    摘要: A lens barrel attached to an imaging device, including a focus lens unit that is movable in an optical axis direction; an actuator that moves the focus lens unit along the optical axis direction; a drive control section that controls drive of the actuator; and a setting section that is capable of setting a movement range of the focus lens unit to be one of a first range and a second range that differ from each other with respect to at least one of one end and another end, each range defining the range in which the focus lens unit is allowed to move. Even when the movement range of the focus lens unit is set by the setting section to be one of the first range and the second range, the drive control section removes the setting of the movement range when instructions are received from the imaging device.

    摘要: An imaging device comprises a lens barrel having an optical system with an adjustable focal point, and has a first state can focus relative to an imaging face, and a second state can not focus relative to the imaging face, a changing unit for changing the lens barrel from the second state to the first state when the imaging unit is activated, a discriminating unit which discriminates whether the state of the barrel is the first state or the second state, and a control unit which, at a time of activating the imaging unit, changes the lens barrel to the first state by the changing unit if it is discriminated that the state of the barrel is the second state, and which maintains the first state if it is discriminated that the state of the barrel is the first state.
