PROBLEM TO BE SOLVED: To provide a lens barrel having satisfactory optical characteristics.SOLUTION: An interchangeable lens 100 includes a fixed frame 60 in which a front movable lens group 4 and a rear movable lens group 6 are coaxially arrayed and movably housed in an optical axis O direction. An intermediate member 40 is disposed between a movable space of the lens frame 11 holding the movable lens group 4 and a movable space of the lens frame 12 holding the movable lens group 6. The intermediate member separates the movable lens groups 4 from the movable lens group 6 to prevent them from interfering with each other, and blocks unnecessary light among light that is incident to the fixed frame 60 and passes through the front movable space to reach the rear movable space.SELECTED DRAWING: Figure 5 |
