An optical device comprises a lens barrel and a casing. The casing has two casing sections that are movable relative to each other. A distribution cable is provided in the casing, and extends between the casing sections. The distribution cable is loosely wound around the lens barrel, whereby a movement of the distribution cable, caused by a relative movement of the casing sections, is absorbed by the loosely wound portion of the distribution cable.
