Abstract
A lens barrel: an optical system; a focusing manipulation unit capable of changing a focal position of the optical system in a normal photographing area and in a macro photographing area where the focal position can be changed for an object located at a position shorter than a shortest distance position of the normal photographing area; a photographing mode switching unit for switching between a normal photographing mode and a macro photographing mode; and an index ring having a normal scale and a macro scale, the normal scale indicating an object distance in the normal photographing mode, and the macro scale indicating the object distance in the macro photographing mode. Then, the photographing mode switching unit switches a display position of the index ring between the normal scale and the macro scale, and the focusing manipulation unit changes the focal position displayed on the index ring by rotation manipulation.
