Abstract: A lens barrel having a fixed outer tube, a distance scale window formed in the outer peripheral surface of the fixed outer tube, a focusing ring which is disposed inside of the fixed outer tube and which is capable of moving in the direction of the optical axis and rotatable about the same, a focusing mechanism for moving the focusing ring in the axial and peripheral directions, a distance scale ring facing the inner periphery of the distance scale window and supported such as to be only rotatable about the optical axis, the distance scale ring having distance scale marks formed on its outer peripheral surface, and an interconnecting mechanism for interconnecting the focusing ring with the distance scale ring. The interconnecting mechanism turns the distance scale ring in response to the turning movement of the focusing ring about the optical axis. Simultaneously, the focusing ring moves in the direction of the optical axis without axially moving the distance scale ring.

Abstract: This invention concerns with the technique of controlling axial movement of a focusing member in the objective lens system based on the signal representing the object distance from the automatic distance measuring means. More particularly, as the provision for manual and automatic focusing modes is made, it relates to a technique of building a mode selection mechanism into the mechanical mounting for the zoom lens.

Abstract: Axial movement of a focusing lens holder is controlled by an output signal of automatic distance measuring means for automatically finding the distance from the means to an object. A lens mounting is selectively operable either by the drive control of the focusing lens holder within the lens barrel by the output signal from the automatic distance measuring means or by the manual drive of the lens holder for visual and manual focusing.

Abstract: A zoom lens barrel which is capable of zoom and close up photography includes a generally cylindrical barrel part, one end of which is mountable to a camera body. Optical system having an optical axis which coincides with the axis of the barrel part is arranged in the barrel part for relative sliding movement to perform zoom and close up photography. A generally cylindrical guide member is coaxially rotatably mounted on the barrel part and has a number of guide slots for engaging the optical system. The guide member also has a guide edge formed on one end, and is axially movable between a first position whereat the guide slots axially guide the optical system relative to the barrel part so that the optical system zooms on an object to be photographed when the guide member is rotated, and a second position whereat the guide member axially displaces the optical system for close up photography of the object. An operation member is mounted on the barrel part next to the guide edge of the guide member for engaging the guide edge of the guide member to move it in the direction of the optical axis between the first and second positions.
