A lens barrel according to the invention comprises a fixed tube fixedly mounted on a camera body, a drive tube fitted with respect to the fixed tube, a data projector fixedly mounted on the camera body for radiating a projecting luminous flux toward a film surface from respective outer peripheries of the fixed tube and the drive tube, to project photographing information, a through bore formed through a portion of the fixed tube through which the projecting luminous flux of the data projecting means passes, and a cut-out provided in a portion of the drive tube which is overlapped with the through bore in the fixed tube upon photographing. Upon non-photographing, a portion of the drive tube having no cut-out shields the through bore in the fixed tube.
