Claim:
1. An image pickup apparatus capable of detachably mounting a lens unit including a plurality of optical members that includes a stop and a focus lens, the image pickup apparatus comprising: an image sensor configured to accumulate charge in synchronization with a vertical synchronizing signal to generate an image signal; and a processor programmed to function as a control unit configured to perform communication in synchronization with the vertical synchronizing signal with the lens unit, wherein the control unit is configured to receive information relating to the optical members from the lens unit in the communication in synchronization with the vertical synchronizing signal, wherein the control unit is configured to generate control information for each of the stop and the focus lens of the mounted lens unit on the basis of the information relating to the optical members from the lens unit, and to transmit the control information for the focus lens to the lens unit in the communication in synchronization with the vertical synchronizing signal at a first timing which is a different timing from a timing to receive the information relating to the optical members, and to transmit the control information for the stop to the lens unit in the communication in synchronization with the vertical synchronizing signal at a second timing which is a later timing than the first timing.
