Image-taking apparatus including lens apparatus operable between housed state and image-taking state |
摘要 |
A lens apparatus is disclosed, which can control the position of a lens unit driven by an actuator such as a vicecoil motor in a non-energizing state of the actuator easily. The lens apparatus comprises: a first lens unit and second lens unit moving in an optical axis direction, respectively; a first actuator driving the first lens unit; and a second actuator driving the second lens unit. The first lens unit is driven by the second lens unit that is driven by the second actuator in a nonenergized state of the first actuator, and a member is provided in one of the first and second lens units. The member contacts the other lens unit in the nonenergized state. |
