    • A method of controlling the focusing of a zoom lens which has a plurality of lens groups including at least one focusing lens group, wherein an amount of deviation from focus caused by a zoom operation is corrected by movement of the focusing lens group. The method includes setting a reference object distance, at which no deviation from focus occurs during zooming of the zoom lens, at a finite object distance, such that the amount of movement of the focusing lens group necessary to effect focusing is determined based upon a reference position corresponding to a position of the focusing lens group at the reference object distance, in accordance with focal length data and object distance data. The zoom lens assembly includes a stationary lens barrel and a rotatable cam ring which is supported on the stationary lens barrel for movement in the direction of the optical axis while being rotated, and which includes at least two cam grooves. The zoom lens includes first and third lens groups which are both movable by one of the two cam groups in a direction of an optical axis. A second lens group movable by a second of the two cam grooves in a direction of the optical axis is also provided, as well as a focusing mechanism for moving the second lens group to a position which is determined by focal length data derived from actual positions of the first, second, and third lens groups and object distance data detected by the object distance measuring device.

    • 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.
