Abstract
An interchangeable lens includes a fixing frame in which a front movable lens group and a rear movable lens group are coaxially arranged and movable in the direction of an optical axis. An intermediate member is arranged between a movable range of a lens frame holding the front movable lens group and a movable range of a lens frameholding the rear movable lens group. The intermediate member is a partition between the movable lens groups and prevents interference between them. In addition, the intermediate member blocks undesired light components which are part of the light incident on the fixing frame and traveling from the front movable range to the rear movable range.
