"The photographing lens 200 is provided on a lens mount 203 thereof with a group of communication/control contacts (lens communication line) 204 and the power contact 205 (VPZ). The group of communication/control contacts 204 and the power contact 205 (VPZ) come into contact with the group of communication/control contacts 104 and the power contact 105 (VPZ) of the camera body 100, respectively, when the photographing lens 200 is mounted to the body mount 103 of the camera body 100 via the lens mount 203. The photographing lens 200 is provided therein with a lens CPU (LCPU/lens controller/electronic device) 211, a lens ROM (LROM/lens memory/nonvolatile lens memory) 221, the encoder 231 and a peripheral circuit 241. Various modes and parameters are stored in the lens ROM 221. A current focal length (zoom code) and a photographic distance are detected via the encoder 231. The peripheral circuit 241 includes, for example, as shown in FIG. 12A, image-shake compensation motors (X-motor 254 and Y-motor 257), the AF motor 261, and a power zoom motor (power zoom driving device) 264, which are all provided in the photographing lens 200. Note that the power zoom motor 264 is connected to a lens group Lz, wherein the lens group Lf and the lens group Lz constitute at least part of a zoom lens system of the photographing lens 200. "
