Abstract
An image pickup system includes a lens apparatus, and an image pickup apparatus to which the lens apparatus is detachably attached. The image pickup apparatus controller changes a cycle of a control reference signal for internal processing of the image pickup apparatus, and sends a command of changing the cycle of the control reference signal to the lens controller in synchronization with a post-change control reference signal. The lens controller that has received the command changes the cycle of the control reference signal when the lens apparatus is ready to change the cycle of the control reference signal, and sends to the image pickup apparatus controller information representing whether the lens controller has been able to follow the change of the cycle of the control reference signal.
