A unit (50, 52, 56, 60) for inputting a set value of a braking characteristic near the end of a zooming operation area, and a storage unit (48) for storing an initial set value are provided for a servo module (lens drive device) (12), and the servo module (12) can change the settings of the braking characteristic. The servo module (12) is detachably mounted to a lens device (10) body and contains a CPU (36), and is provided with A/D converters (30, 32) for A/D converting an analog control signal and a lens position signal for focus and zoom from the lens device (10) body, and a digital signal communications interface (34). A parameter value of the braking characteristic can be changed by operating a switch unit (50). Memory (48) stores an initial set value of the braking characteristic, and the initial set value can be restored as necessary. In addition, an indicator (lens status display portion) (14) mounted in the lens device (10) body is used as a unit for checking the parameter value of the braking characteristic. <IMAGE> |
