Abstract:
PROBLEM TO BE SOLVED: To provide an optical apparatus able to perform automated discrimination of permission or rejection of set data copying for each function on the basis of a comparison result of own lens specifications information with lens specifications information of a different optical apparatus, in order to prevent lens malfunction after copying the set data between the different optical apparatus.SOLUTION: A lens device includes: storage means for storing set data related to functions of the lens device; communication means for communicating with another lens device; and control means for controlling setting of setting data and transmission of the setting data by the communication means. The control means determines whether the communication means transmits the set data to the another lens device or not for each of the set data on the basis of specifications information of the lens device and the another lens device, and sets setting data on the basis of received set data if the communication means has received the set data from the another lens device.
