Imaging apparatus, flash device, and control method thereof

摘要

An imaging apparatus for performing wireless communication with an external device. An instruction transmitting unit transmits an operation instruction to the external device. A response signal receiving unit receives a response signal from the external device. A first controlling unit starts a first operation relating to an imaging process in a case that a first time passes from a point of receiving the response signal by the response signal receiving unit. The external device executes a second operation relating to the imaging process in a case that a second time passes from a point of transmitting the response signal from the external device to the imaging apparatus.
