发明名称 Optical apparatus with image stabilizing and movable lenses and actuators for shifting and/or moving the lenses
摘要 The optical apparatus includes an image stabilizing lens shiftable with respect to an optical axis, a movable lens movable in an optical axis direction, first and second actuators shifting the image stabilizing lens, and a third actuator moving the movable lens. The first, second and third actuators include a magnet and a coil. When viewed in the optical axis direction, the first and second actuators are disposed in a first area and the third actuator is disposed in a second area, the first and second areas being opposite to each other with respect to the optical axis. The first and second actuators are respectively disposed in areas in the first area opposite to each other with respect to a straight line passing the optical axis and the third actuator. This arrangement enables reduction of magnetic interference between the first and second actuators and the third actuator.
