Patent ID: 8090247

Claim:
A lens barrel, comprising: a shooting optical system; a movable optical member that is part of the shooting optical system or which is another optical member, and which is provided movably relative to the shooting optical system; a vibration reduction unit including a first actuator that drives the movable optical member and a magnetic sensor configured to detect a position of the movable optical member; and a second actuator different from the first actuator, the second actuator including a coil having a winding center line of a winding wire provided in a direction that intersects with a direction in which a sensitivity of magnetic detection of the magnetic sensor is the highest, wherein the first actuator is disposed on one side of the movable optical member and the coil is disposed on an opposite side of the movable optical member such that the movable optical member is sandwiched between the first actuator and the coil, the second actuator is provided such that at least part of the second actuator overlaps the vibration reduction unit in a direction of an optical axis of the shooting optical system, and the winding center line of the winding wire is situated substantially in parallel with and in substantially the same plane as a plane in which the magnetic sensor is disposed.
