Abstract:
1. An optical apparatus comprising: an anti-shake lens capable of shifting with respect to an optical axis of an optical system; a movable lens unit, which includes a movable lens, capable of moving along the optical axis; a light intensity controlling member configured to control light intensity passing through the optical system; first and second actuators, each of which includes a magnet and a coil, configured to shift the anti-shake lens in directions different from each other; a third actuator, which includes a magnet and a coil, configured to move the movable lens along the optical axis, wherein either the coil or the magnet is fixed on the movable lens unit; a fourth actuator configured to operate the light intensity controlling member to the light pass; and a barrel member which contains the anti-shake lens, the movable lens, the light intensity controlling member, and the first to the fourth actuators, wherein the first to the fourth actuators are disposed inside the barrel member so as not to overlap with one another when viewed in an optical axis direction.
