An imaging apparatus includes a communication unit that executes data communication with a predetermined number of external devices, a search unit that searches for external devices that can executes data communication with the imaging apparatus, and a determination unit that, if the search unit finds a number of external devices that is greater than the predetermined number, determines with which of the external devices communication is to be activated. The determining unit is configured to, in case that the imaging unit executes an imaging process, preferentially activate communication with external devices that are used in the imaging process.
