摘要:
An imaging system includes an interchangeable lens and a camera body. The camera body includes a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens and delay time information indicating delay time with respect to the reference signal, to the interchangeable lens. The interchangeable lens includes a lens controller operable to control the focus lens to be driven at a timing obtained by delaying the timing provided by the reference signal by the delay time based on the reference signal and the delay time information received from the main body controller. The delay time is set so that, for example, an exposure timing of a predetermined area in the imaging element is substantially coincident with a stop period of the wobbling operation of the focus lens.
