Abstract:
A zoom lens barrel assembly for a zoom lens which is driven to achieve both focusing and zoom ratio adjusting of the zoom lens, said zoom lens barrel assembly comprising:a rotatable driven lens barrel;a first lens guide mechanism for shifting at least one lens group of said zoom lens to achieve focusing of said zoom lens, the first lens guide mechanism being connected to the rotatable driven lens barrel;a second lens guide mechanism for shifting at least said one lens group of said zoom lens differently from said first lens guide mechanism to adjust a zoom ratio of said zoom lens, the second lens guide mechanism being connected to the rotatable driven lens barrel; andan electrically operated clutch mechanism for selectively actuating said first and second lens guide mechanisms;wherein each of the first and second lens drive mechanisms is actuated by rotation of the rotatable driven lens barrel.
