Abstract
The image-capturing apparatus includes a controller that provides, by switching a signal level of an RTS channel from a first level to a second level, a transmission request to an accessory to cause the accessory to transmit accessory data to the image-capturing apparatus through a DLC channel and transmits camera data to the accessory through a DCL channel. The controller selectively performs a first process to switch, after the accessory receiving the transmission request starts transmitting first accessary data, the signal level from the second level to the first level, and a second process to keep, after the accessory receiving the transmission request ends transmitting the first accessary data, the signal level at the second level. The controller receives, while keeping the signal level at the second level in the second process, second accessory data different from the first accessory data.
