PURPOSE:To prevent misoperation by providing a signal member which performs lens identification and a member which responds to this. CONSTITUTION:A pin-form signal member 12 is protrusively provided in the optical axis direction to the rear end of a lens 11 of automatic focusable brightness by the automatic focus mechanism to the camera body 10 side. A responding member 14 which has an index 15 is provided within the mount part 13. As a result of this, when the lens 11 of automatic focusable brightness is mounted to the camera body 10, the responding member 14 is moved in the arrow direction by its signal member 12 and the index 15 indicates the fully automatic focusing FA or semiautomatic focusing SA displayed in the finder visual field 16. On the other hand, the mounted lens is infeasible of automatic focusing because lack of signal member 12, the responding member 14 stays in the position indicating the manual M. |
