Abstract:
To prevent a motor for driving a diaphragm from interfering with a moving range of a lens group even when a diaphragm unit and an anti-vibration unit are provided to be adjacent to each other in an optical axis direction.SOLUTION: A zoom lens barrel 1 comprises: a diaphragm unit 16 that has a motor 34 for driving a diaphragm and has a central opening whose radius is changed by the motor 34 for driving a diaphragm; and an anti-vibration unit 14 that has a fixed member 50 and a movable member 40 for holding an image-blurring correcting lens group C and that is for preventing image blurring by movement of a movable member 40 relative to the fixed member 50. In the zoom lens barrel 1, the diaphragm unit 16 is provided to be adjacent to the anti-vibration unit 14 in an optical axis direction. The motor 34 for driving a diaphragm of the diaphragm unit 16 protrudes to the side of the anti-vibration 14, and is provided in parallel with the anti-vibration unit 14 in the optical axis direction.SELECTED DRAWING: Figure 7
