Abstract

The invention provides an imaging apparatus, an accessory apparatus, and a storage medium. The imaging apparatus includes a camera communicator connected to a signal communication channel and a data communication channel; and a camera controller configured to perform a signal communication with the plurality of accessory apparatuses using the signal communication channel, and a first communicationthat is a data communication with the plurality of accessory apparatuses and a second communication that is a data communication with a first accessory apparatus among the plurality of accessory apparatuses, using the data communication channel. The camera controller notifies a second accessory apparatus other than the first accessory apparatus of a communication prohibition by the second communication, and then notifies a change of a clock rate of at least one of the first communication and the second communication via the second communication to change the clock rate.

Description

technical field [0001] The present invention relates to an imaging (camera) system including an imaging device (hereinafter referred to as a camera body) capable of communicating with each other and accessory devices such as an interchangeable lens and an adapter, and a storage medium. Background technique [0002] In an interchangeable lens type camera system including a camera body capable of detachably attaching an interchangeable lens, controlling the operation of the interchangeable lens for the camera body and providing data necessary for its control and imaging to the camera body for the interchangeable lens are performed. communication. In particular, when using an interchangeable lens to capture a moving image for recording and a moving image for live view display, smooth lens control is required in the imaging cycle, so it is necessary to match the imaging timing of the camera body and the control timing of the interchangeable lens to each other. Synchronize. The...
