摘要： An auto-focus control camera includes an arrangement for measuring distance to a subject to be photographed, a calculator for calculating the degree of out of focus and an actuator for actuating a motor that shifts camera picture taking lens to a proper focus position according to the calculated result. The auto-focus control camera further includes a detector for detecting a time it takes for the arrangement of distance measuring and calculator to complete its operation. If the detected time is within a predetermined time period, the actuator is made operative to complete the photographing operation with auto-focusing, and if the detected time is longer than the predetermined time period, the photographing operation is carried out without auto-focusing.

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。
