ABSTRACT:
An optical apparatus includes an anti-shake lens L3shifting with respect to an optical axis AXL of an optical system, a movable lens L4moving along the optical axis, a light intensity controlling member5controlling light intensity, first and second actuators including magnets33aand33band coils34aand34b, respectively, which shifts the anti-shake lens to directions different from each other, a third actuator including a magnet63and a coil54which moves the movable lens, a fourth actuator51which operates the light intensity controlling member, and a barrel member7which 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.
