PROBLEM TO BE SOLVED: To employ a demand having no autofocus operation function for an autofocus lens.SOLUTION: When a focus demand is connected to the lens device, the device determines whether a demand has an autofocus operation function in S1. When the demand has the autofocus operation function, the process proceeds to S2, and focus processing is executed. In S2, when autofocus is disabled, a focus movement lens group is driven with a focus signal from the demand. When autofocus is enabled, the lens group is driven with a focus signal of a camera device. When the demand has no autofocus operation function, the process proceeds to S3, the presence of a rotation end of an operation knob of the demand is determined, and processing is executed for presence of the rotation end in S4 or for absence of the rotation end in S5. Next, in S6, the process proceeds to S2 according to function assigning processing to an autofocus ON/OFF operation of a command signal of a return switch, and focus control is executed. |
