<p>PROBLEM TO BE SOLVED: To provide an interchangeable lens that enables appropriate through-images to be provided to users by a camera body.SOLUTION: An interchangeable lens comprises: an optical system; a tremor correction actuator that moves a part of lenses included in the optical system in a vertical plane of an optical axis to thereby make a tremor correction; a detection part that detects whether the optical system is in an extending state or in a collapsed state; a first transmission unit that, when detecting a change from the extending state to the collapsed state, transmits a signal indicative of the collapsed state to a camera body, and then, turns off power to the tremor correction actuator; and a second transmission unit that, when detecting a change from the collapsed state to the extending state, turns on the power to the tremor correction actuator, and then, transmits a signal indicative of the extending state to the camera body.</p> |
