Abstract
An imaging system includes an interchangeable lens and a camera body. The camera body includes a second communication unit capable of communicating with a first communication unit, an imaging element operable to generate an image signal from the optical image, and a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens to the lens controller through the second and first communication units. The main body controller transmits the reference signal to the lens controller during a period for which neither communication of predetermined signals other than the reference signal nor process related to the communication is performed between the first communication unit and the second communication unit.
