摘要： A zoom lens in which a stop guide is located between an operating ring and a stationary lens barrel for regulating the range of rotation of the operating ring. A macrophotography guide permits, when the operating ring is positioned at the closest photographing distance and in the focusing rotation range and at at least one of the zooming movement ends, the operating ring to further turn for a closer photographing range. The stop guide includes a stop pin fixed to the operating ring and a stop plate having stop pin rotation range regulating surfaces on both sides in the circumferential direction of the zoom lens and which is secured to the stationary lens barrel. The plate has a macrophotography guide cut formed in at least one end portion located in the direction of the optical axis with the macrophotography guide cut being arranged circumferentially of the zoom lens.

摘要： A camera body having a camera body and an interchangeable lens engageable with the camera body has an improved contact arrangement between camera body and lens. A lens mount has a first flat surface, a camera mount engages a lens mount to join the lens to the camera body, and the camera mount has a second flat surface abutting the first flat surface when the lens mount engages the camera mount. One or more first electrical contacts in the lens mount are movable normal to the first surface between a retracted position approximately flush with the first surface and an extended position projecting from the first surface. A spring urges the one or more first contacts toward the extended position. One or more stationary second electrical contacts in the camera mount open toward the second surface without protruding therefrom in alignment with the respective one or more first contacts when the lens mount engages the camera mount so the one or more first contacts normally bear against the respective one or more second contacts. A manually actuated device retracts the one or more first contacts into a position spaced from the respective one or more second contacts. The lens mount and the camera mount are electrically conductive so the manually actuated device connects and disconnects the one or more first contacts electrically to and from the lens mount to make and break electrical contact between the one or more second contacts and the mounts.

摘要： A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well as into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.

摘要： A zoom lens for a camera having a between-the-lens shutter includes a motor for moving the lens along an optical axis in forward and rearward directions. A switch is operable by an operator to control operation of the motor for moving the lens from an initial position on the axis to a final stationary position that establishes the focal length of the lens. Control apparatus is responsive to the setting of the switch for operating the motor such that movement of the lens from its initial position to its final position always ends after the lens travels to its final position in a predetermined direction.

摘要： An electrically driven zoom lens barrel is provided with an indicating plate for indicating whether a zooming operation is being carried out in an electric mode or in a manual mode. The indicating plate is provided separately from a zooming operation ring, which is moved forwardly and rearwardly to switch a zooming operation between the electric mode and the manual mode. The indicating plate displays the manual mode when the zooming operation is carried out in the manual mode, and displays the electric mode and a zooming speed and direction, when the zooming operation is carried out in the electric mode.
