Abstract
A lens apparatus is detachable from an image pickup apparatus. The lens apparatus includes a controller configured to communicate with the image pickup apparatus in synchronization with a first signal. A communication contains a plurality of blocks in the same cycle of the first signal. The controller transmits information of a first time period to the image pickup apparatus, and prohibits a communication of an m-th block from starting before the first time period passes after a communication of an n-th block starts or ends where n is an integer equal to or larger than 1 and m is an integer larger than n.
