A relay unit connected between a remote control unit and an optical device having a focus lens comprises a first switching signal input unit for switching control of the focus lens between automatic focal point detection focusing and control of the focus lens by remote commands from the remote control unit. This enables remote control of a lens unit simply by replacing the lens unit with one having automatic focus capabilities.
