摘要： Lenses, which include at least one plastic lens, are supported in a lens barrel by a lens holding structure which includes shoulder surfaces and inner circumferential surfaces of a lens barrel, at least one annular elastic member, and a retainer ring. The lenses are radially positioned in coaxial alignment with the lens barrel by the inner circumferential surfaces of the lens barrel, and axially positioned in engagement with the shoulder surfaces by the elastic member and the retainer ring. The elastic member elastically presses one of the lenses against one of the shoulder surfaces, and the retainer ring is threadedly mounted on the outer end of the lens barrel end holds the other lens against the other shoulder surface. Annular spacers may be disposed between the outer circumferential edges of the lenses and the inner circumferential surfaces of the lens barrel, for holding the lenses in coaxial alignment with the lens barrel.

摘要： A lens barrel includes: a variable-power optical system including a focus lens group; a focus actuator configured to move the focus lens group supported by a support forward or backward in a direction of the optical axis to change a shooting distance; and a moving unit configured to, in response to receiving a driving force for changing a zoom magnification, move a position of the focus lens group in the direction of the optical axis to a position corresponding to the changed zoom magnification. The moving unit is configured to move the focus lens group in the direction of the optical axis by the driving force such that a change in a shooting distance due to a change in the zoom magnification is within a predetermined tolerance when the focus lens group is at a position corresponding to the minimum shooting distance, at every zoom magnification.

摘要： A lens barrel includes a linear guide ring; a linearly movable ring which is provided inside the linear guide ring and has a cam on an outer circumferential surface; and a hand-operated rotating ring, provided outside the linear guide ring, which is capable of rotating in a circumferential direction and is incapable of rotating in an optical axis direction, with respect to the linear guide ring and which has a first penetrate groove. The linear guide ring, the linearly movable ring and the hand-operated rotating ring are provided concentrically to each other. A rotation motion of the hand-operated rotating ring with respect to the linear guide ring causes the linearly movable ring to move linearly along the optical axis direction, via the linear guide ring. The linear guide ring has a second penetrate groove penetrated in a radial direction. A projection member, which is to be engaged with the cam provided on the linear movable ring, via the second penetrate groove of the linear guide ring, is inserted from an outside of the hand-operated rotating ring.
