摘要： A lens position control device for a lens system, the lens system including a variator and a compensator which also serves as the focusing lens, includes a detecting circuit for detecting the position of the variator and the focusing lens, a memory for storing information representing a plurality of values of the speed of movement of the focusing lens determined depending on the positions of the variator and the focusing lens and a predetermined value of the speed of movement of the variator, and a control circuit responsive to zoom actuation for controlling the movements of the variator and the focusing lens. Depending on the information representing the positions of the variator and focusing lens determined by the detecting circuit, the control circuit selects a specific one of the values of the moving speed from the memory so that the focusing lens moves at the particular speed, and the movements of the variator and the focusing lens are started at almost the same time.
