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.
摘要翻译：可拆卸地安装在具有自动聚焦装置的照相机主体上的可交换透镜组件选择性地能够通过自动聚焦装置的操作进行自动聚焦调节或通过手动操作进行手动对焦调节。在两个实施例中，通过与手动聚焦环分开设置在固定镜筒上的转换构件的操作来进行自动对焦调节和手动对焦调节之间的切换。在手动对焦调整的情况下，与焦点调节机构联动的从动轴与自动聚焦装置的驱动轴脱离。在其余实施例中，相对于固定筒可旋转和可轴向移动的手动聚焦环在自动对焦位置和用于切换的手动聚焦位置之间轴向移动。当环移动到自动聚焦位置时，与焦点调节机构联接的从动轴与自动聚焦装置的驱动轴接合，并且环从聚焦调节机构脱离联接。当环移动到手动聚焦位置时，被驱动轴和驱动轴之间的接合被中断，并且环由于弹性构件的弹性变形而通过摩擦接合与聚焦调节机构联接。

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： As improved mounting device for an optical unit consists of two optical components, one of which is mounted on the other, or else demounted therefrom, by relative rotation of the two with sliding contact of mating seating and mounting faces thereof, wherein in the seating face of the one optical component is formed a positioning recess which is engaged by a positioning member of the other optical component. The positioning member is constantly urged to project beyond the associated mounting face when the other optical component is properly mounted on the one optical component. Along a circular path on the seating face adjacent to the positioning recess is provided an accommodation groove which accommodates the positioning member when the one optical component is turned relative to the other optical component.

摘要： An auto-focusing system includes a focus condition detector which detects focus condition based on the infrared light. A data producer is provided for producing a deflection signal indicating a difference between an image forming distance for the infrared light and that for the visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.
