    摘要: A camera system with an auto-focusing system includes a camera body and an interchangeable zoom lens. The interchangeable objective lens stores various data to be sent to the camera body for improving automatic focus adjustment, such as an information necessary to convert the detected defocus information into a movement of the driving power source to carry out the automatic focus adjustment. The driving power source in the camera body is controlled in response to the data from the interchangeable objective lens and the detected focus information, the driving power being transmitted to the interchangeable objective lens. The camera body is further capable of inhibiting the focus adjustment or focus indication in response to a data from the interchangeable objective lens under an unfavorable condition.

    摘要: A lighting device such as an electronic flash device attachable to a camera body includes first and second light projecting optical systems which project first and second light fluxes for illuminating an object to aid focus detection by a focus detection device. The second light flux spreads at a larger solid angle than the first light flux and illuminates a fist distance zone which extends to a closer distance side while covering the whole of a second distance zone illuminated by the first light flux. An optical wedge disposed in the second light projecting optical system deflects a part of the second light flux towards the closer distance side of the first distance zone. Another lighting device includes a single light projecting optical system but it also includes an optical wedge for deflecting a part of a light flux projected by the light projecting optical system to widen a distance zone illuminated by the light flux towards a closer distance. The optical wedge also serves to produce a difference in intensity distribution of the light flux such that the light flux has higher intensity at a part thereof for illuminating a farther distance side of the distance zone than at a part thereof for illuminating a closer distance side of the distance zone. A light source of the light projecting optical system(s) is provided with a conical light reflector surrounding a light emitting diode to reflect light emitted from side surfaces of the light emitting diode forward.

    摘要: An automatic focus control camera is provided having a lens driven by a motor. The lens can be driven to an in-focus position during an actual film exposure operation if the exposure time is relatively fast enough with regard to the movement of the lens. Alternatively, the lens can be stopped immediately preceding the actual film exposure operation depending upon the measured exposure parameters.

    摘要: An exchangeable lens assembly detachably mountable on a camera body having an automatic focusing device is selectively capable of either automatic focus adjustment by the operation of the automatic focusing device or manual focus adjustment by a manual operation. In two of the embodiments, the change-over between the automatic focus adjustment and the manual focus adjustment is made by operation of a change-over member provided on a stationary barrel separately from a manual focusing ring. A driven shaft coupled with a focus adjusting mechanism is disengaged from a driving shaft of the automatic focusing device in the case of the manual focus adjustment. In the remaining embodiments, a manual focusing ring rotatable and axially shiftable relative to a stationary barrel is axially shifted between an automatic focusing position and a manual focusing position for the change-over. When the ring is shifted to the automatic focusing position, a driven shaft coupled with a focus adjusting mechanism is engaged with a driving shaft of the automatic focusing device and the ring is un-coupled from the focus adjusting mechanism. When the ring is shifted to the manual focusing position, the engagement between the driven and driving shafts is interrupted and the ring is coupled with the focus adjusting mechanism by frictional engagement due to elastic deformation of a resilient member.
