The lens device has: the main body member 1005; a scale member 1027 that rotates in a direction around the optical axis in conjunction with a movement of a focus adjustment lens; and the exterior member 1002 that is mounted into the main body member, and provided with a window part 1026 making a distance scale viewable and an index 1027a indicative of a focus distance. The exterior member and the main body member have an adjustment structure 1028 that enables a position adjustment in the direction around the optical axis of the exterior member to the main body member for adjusting a position of the index to the distance scale in a state where the exterior member is semi-mounted to the main body member by the attachment member 1029.</p> |
