Abstract:
1. A camera apparatus to which a lens unit is attachable/detachable, the lens unit containing at least a lens and an iris, and containing a memory storing lens characteristics data required for operating the lens and the iris, the apparatus comprising: a communication part capable of communicating data with respect to the lens unit; a mounting detector that monitors attachment/detachment of the lens unit, and outputs first detection information when the lens unit is mounted; a controller capable of acquiring the lens characteristics data from the lens unit via the communication part and outputting second detection information when acquiring the setting information; a first storage that stores either the first detection information outputted from the mounting detector or the second detection information outputted from the controller; and a second storage capable of storing the lens characteristics data acquired by the controller, wherein the controller checks detection information stored in the first storage at a time of start-up of the camera apparatus, when the first detection information is stored in the first storage, controls so that the lens characteristics data is acquired from the lens unit, and when the second detection information is stored in the first storage, controls so that the lens characteristics data is acquired from the second storage.
