ABSTRACT:
A stationary barrel attached to a camera body, a first movable barrel, a second movable barrel and a third movable barrel are moved out successively. A first lens frame holding a first lens unit is held in the third barrel to be movable along the optical axis, and a second lens frame holding a second lens unit is held in the second barrel to be movable along the optical axis. With this arrangement, the three movable barrels are all housed in the stationary barrel, and the total moving-out mount of the three movable barrels is remarkably large compared to conventional arrangements.
