Abstract:
An optical apparatus includes an anti-shake lens L3 shifting with respect to an optical axis AXL of an optical system, a movable lens L4 moving along the optical axis, a light intensity controlling member 5 controlling light intensity, first and second actuators including magnets 33a and 33b and coils 34a and 34b, respectively, which shifts the anti-shake lens to directions different from each other, a third actuator including a magnet 63 and a coil 54 which moves the movable lens, a fourth actuator 51 which operates the light intensity controlling member, and a barrel member 7 which contains the anti-shake lens, the movable lens, the light intensity controlling member, and the first to the fourth actuators. 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.
