Abstract
In a program reset processing, a camera confirms stopping of the lens by a focus lens drive state obtaining communication. Then, a lens request obtaining communication is performed. When the lens can return to the AF mode and is in the MF mode, an 'AF/MF switch instruction' is transmitted. When a 'lens request obtain' communication is performed and it is confirmed that the mode has been switched to the AF mode, 'mechanism resetting' is performed. Thus, troubles in setting the focus mode can be prevented.
