PROBLEM TO BE SOLVED: To provide a zoom lens device which has a structure for performing a zoom operation by individually driving a plurality of zoom lens groups by respective actuators, and has a zoom function capable of preventing image quality deterioration due to a zoom operation during moving image shooting.SOLUTION: The zoom lens device includes: a first ZM group driving part 115 for moving a first zoom group 105; a second ZM group driving part 117 for moving a second zoom group; a storage part 133 for storing positional information of the first and second lens groups corresponding to a zoom lens focal distance and information on the moving speeds of the first and second lens groups; and a control part 131 for controlling the positions of the first and second lens groups on the basis of the positional information of the first and second lens groups, and controlling the first and second driving parts so that the first and second lens groups move while their moving speeds are synchronized with each other on the basis of the information on the moving speeds of the first and second lens groups. |
