Abstract
An imaging apparatus on which an accessory is mountable includes a control unit configured to control first communication with the accessory via a first communication unit and second communication with the accessory via a second communication unit, and, in a case where a communication error in the second communication is detected, perform communication retry processing that repeats transmission of data up to a predetermined number of times until the communication error is resolved. In the case where the communication error in the second communication is detected, the control unit issues a notification corresponding to the communication error to a user without performing the communication retry processing in a case where information corresponding to the fact that the accessory does not receive the data via the second communication is received via the first communication.
