摘要：A control apparatus (113) for an optical apparatus (116) that includes a movableoptical element (105), an endlessly rotatable operation ring (115) and a driver (112)
configured to drive the optical element includes an operation start detector (113)configured to detect a start of an operation of the operation ring, and a drive controller(113) configured to control the driver. The drive controller sets a rotational position ofthe operation ring and the position of the optical element to a ring reference positionand an optical element reference position respectively when the start of the operation ofthe operation ring is detected. The drive controller controls the driver in accordance witha drive amount of the optical element calculated with an operational amount of theoperation ring from the ring reference position, and the optical element referenceposition.
