Abstract
An accessory apparatus, removably attached between an image capturing apparatus and an interchangeable lens, performs first communication with the image capturing apparatus and second communication with the interchangeable lens, and accepts a predetermined operation for operating a predetermined function that assists an autofocus (AF) operation. The accessory apparatus implements the predetermined function by controlling transmission of a control command to the interchangeable lens based on the predetermined operation and the control command for the AF operation accepted from the image capturing apparatus. To control the transmission of the control command, the accessory apparatus does not transmit a control amount included in the control command and pertaining to focus for the AF operation to the interchangeable lens, or changes the control amount and transmits the control amount changed to the interchangeable lens.
