摘要： An extension tube for a photographic lens having a diaphragm preselection ring and a diaphragm blade ring resiliently urged into the position of the smallest diaphragm aperture. The tube is provided with a preselection ring and with an inner ring of its own. Interengaging means on the lens and on the extension tube keep the lens preselection ring arrested in its position of the smallest diaphragm aperture when the lens is mounted on the extension tube. The extension tube inner ring is provided with a first stud on its front and with a second stud on its rear, both studs extending in axial direction. The front stud engages the lens diaphragm blade ring and the rear stud engages the camera diaphragm lever so that the action of the camera diaphragm lever is transmitted through the extension tube to the lens diaphragm blade ring and the diaphragm preselection operation of the lens is maintained when the extension tube is inserted between the lens and the camera body.

摘要： A single lens reflex camera having interchangeable lenses, an exposure meter capable of carrying out photometering of the light through a phototaking lens according to the system of the lens attached. A sliding cam plate is movable to a position corresponding to a preset value of a diaphragm aperture by the engagement of an interchangeable lens with a preset pin. A rocking lever is engageable with the sliding cam plate for positioning at a predetermined location in accordance with the location of the preset pin for adjusting the exposure meter to open aperture photometry, and a sliding member is operatively engageable with an aperture setting pin of the lens. A setting lever is connected to the sliding member for setting the aperture to a preset value, a portion of the setting member being engageable with the rocking lever when the setting lever is actuated to set the exposure, thereby to pivot the rocking lever for adjusting the exposure meter to open aperture photometry. A warning member in operative association with the rocking lever is movable between a warning range and a photometry range.

摘要： An automatic exposure control system for a single lens reflex camera, in which provision is made such that after the operations of focusing and the like have been carried out with the diaphragm opened at its maximum aperture, the shutter button is depressed so that the diaphragm may be closed to a predetermined aperture stop value simultaneously with the jump up of the reflector mirror and the amount of light passed through the lens may be measured by means of a photo-conductive element located behind the mirror to achieve the time control for the shutter speed.

摘要： An interchangeable lens capable of change over between automatic and manual diaphragm stop operations includes a diaphragm actuator ring and an automatic diaphragm interlocking member. Said actuator ring is normally urged in stop-down direction and engaged by said interlocking member which normally holds the actuator ring in a fully opened position with the aid of a spring being driven by a stop lever in a camera for automatic aperture stop operation. The interlocking member is displaceable to a position beyond its operating range and is clamped in that position for manual aperture stop operation, whereby the lens can be readily and simply changed over between automatic and manual stop operations.

摘要： 1,109,192. Diaphragm setting means. M.C. SCHNEIDER and H.J. SCHNEIDER [trading as JOS. SCHNEIDER & CO. OPTISCHE WERKEJ. April 1, 1966 [April 3, 1965], No. 14436/66. Heading G2A. A diaphragm-stop pre-selector is jointly controlled by two independent selectors each having a plurality of positions representing different values of respective variables (e.g. film sensitivity, distance or focusing range), the setting means associated with these selectors having respectively different degrees of freedom. The range selector is a ring (9) on the housing (1) of the camera Fig. 1 (not shown) carrying a scale (9a) reading against a fixed mark on the camera. Rotation of this ring (9) is transmitted, via threaded rings (8, 7 and 16) into axial movement of the objective lens (31) for focusing purposes. A spring-loaded rod 4 slides axially in a bore (1a) in the housing, and its forward end bears against the face of a ring 5, said face being formed as a cam surface. A lug 12 fixed to the ring (9) engages in a cut-out 5b on ring 5, so that ring 5 rotates with the first ring (9), and thus rod 4 moves axially with the cam surface on ring 5 in accordance with the distance setting. Also mounted on the camera housing is a sensitivity-selector ring (10), actuated by a knob (11), and reading against a film-sensitivity scale. Ring 10 has a diagonal cam-slot 10a which receives a stud 5a projecting from ring 5. Thus rotation of ring 10 results in an axial movement of ring 5, and hence of rod 4. Thus ring 5 receives a rotational movement from the first ring (9) (distance setting) and an axial movement from ring 10 (film-speed setting), both of these affecting the axial position of rod 4. The diaphragmsetting mechanism includes a rotatable ring 15, having an extension 15b with a stepped profile 15c. The diaphragm is normally maintained in a fullyopen position, and closed to the selected position only when the shutter release is pressed. This selected position is determined by the position of rod 4, which will arrest the movement of ring 15 according to which part of the stepped profile 15c it is in alignment with. The ring 15 may, if desired, be de-coupled and adjusted manually.
