PROBLEM TO BE SOLVED: To provide a lens barrel and an optical device in which lock operations of plural movement members to a lens barrel and lock release operations thereof can be properly performed.SOLUTION: In a lens barrel and an optical device, when a first lens holder is moved in a direction to get away from a first lock position (R2), first magnetic characteristics are changed by a magnetic field generated by a first drive coil, and second magnetic characteristics are changed by a magnetic field generated by a second drive coil, so that the adsorption power between a first lock magnetic material and a lock magnet is reduced. |
