Abstract: A lens barrel includes a support frame and a retracting lens frame. The support frame includes a main body portion, a first linking portion and a second linking portion. The first region is configured to dispose the second lens in the imaging enabled state. The second region is formed continuously with the first region. The first linking portion links the second region on one side of the main body portion in the optical axis direction. The second linking portion links the second region on the other side of the main body portion in the optical axis direction. The retracting lens frame is disposed between the first linking portion and the second linking portion in a housed state.

Abstract: A lens barrel includes a first lens, a second lens, a first frame body, a second frame body, and a retracting lens frame. The retracting lens frame is configured to move so that a position of the second optical axis of the second lens changes from a position on the first optical axis of the first lens to a position that is outside the first optical axis, during the transition period between the imaging enabled state and the housed state. A contact portion is formed on the inner peripheral part of the first frame body. A protrusion of the retracting lens frame is configured to engage with and guided by the contact portion during movement of the retracting lens frame. The thickness of a region constituting the side wall of the contact portion is increased over the thickness of the other region toward the inside of the cylindrical part.

Abstract: There is provided a lens barrel capable of suppressing deformation of a rear frame upon application of a radial inward force to the rear frame. The lens barrel is a lens barrel attachable to a camera body. The lens barrel includes a lens mount mechanically or electrically connected to the camera body, a fixed frame fixed to the lens mount, and a rear frame that covers an outer periphery of the fixed frame. The rear frame has a tubular portion and flanges that extend from a front end and a rear end of the tubular portion radially inward, and at least a part of a radial inner end of the flange is brought into contact with the fixed frame.

Abstract: A lens barrel is detachably attached to a camera body, and includes an exterior unit, a rear frame, a tripod mount, and a tripod lock screw. The exterior unit includes an optical system. The rear frame is mounted to the exterior unit so as to be rotatable around an optical axis. An outer peripheral surface of the lens barrel is configured with the exterior unit and the rear frame. The tripod mount is provided on the rear frame to be fixed to a tripod. The tripod lock screw fixes a rotational position around the optical axis of the rear frame to the camera body at a predetermined rotational position, in a state in which the lens barrel is mounted to the camera body.

Abstract: A lens barrel includes a first lens frame that holds a first lens; a second lens frame that holds a second lens, and holds the first lens frame movably along an optical axis; and a pair of linear units that drive the movement of the first lens frame along the optical axis. When seen in an optical axis direction, the pair of linear units are disposed along the outer circumference of the first lens frame, at mutually non-opposing positions across the optical axis.

Abstract: A lens barrel includes a tip member, a lens hood, and a sliding member. The tip member is disposed on a subject side in an optical axis direction, and includes an optical system. The lens hood moves between a storage position and a use position in the optical axis direction. The sliding member is provided on an inner circumferential surface side of the lens hood. When the lens hood moves from the storage position to the use position, the sliding member moves to the subject side in the optical axis direction in a state where the sliding member is in contact with an outer circumferential surface of the tip member. In a state where the lens hood is located at the storage position, an interval of at least a portion of a clearance formed between the inner circumferential surface of the lens hood and the outer circumferential surface of the tip member is narrowed toward the subject side in the optical axis direction.

Abstract: A lens barrel includes a first frame body, a second frame body, a support frame, and a retracting lens frame. The support frame is supported by the second frame body and moves with respect to the second frame body within a first plane for image blur correction in an imaging enabled state, the first plane being perpendicular to an optical axis. The retracting lens frame moves around a retraction shaft during a transition period between an imaging enabled state and a housed state, the retraction shaft being substantially parallel to the optical axis. The support frame has a protrusion which comes into contact with a groove included in the first frame body and restricts a movable range of the support frame in the first plane and a second plane that is parallel to the first plane.
