摘要： An exchangeable lens includes: a mount unit at which a camera body is detachably engaged; a plurality of drive target members, conditions of which change as a drive force is applied thereto; an initialization unit that executes initialization processing for each of the plurality of drive target members; an initialization status transmission unit that transmits initialization statuses, each indicating a status of the initialization processing executed for one of the drive target members, to the camera body via a first transmission path over predetermined first cycles; and a drive condition transmission unit that transmits a drive condition of at least one drive target member among the plurality of drive target members to the camera body via a second transmission path different from the first transmission path over predetermined second cycles different from the predetermined first cycles.
