    • An automatic focusing camera is equipped with an automatic subject distance detecting device for detecting which of a plurality of predetermined distances is nearest to that at which the subject lies. A lens positioning member adjusts an objective lens to a suitable focusing position in which the objective lens has a depth of field straddling that nearest predetermined distance detected by the automatic subject distance detecting device. Another lens positioning member adjusts the objective lens to a focusing position in which the objective lens will be focused on a subject, such as a landscape, at infinity, independently of the distances detected by the automatic subject distance detecting device. The latter objective lens positioning member is externally operable when it is intended to photograph a subject at infinity, before depressing the shutter button.
    • 自动聚焦照相机配备有自动被摄体距离检测装置,用于检测多个预定距离中的哪一个距离被摄体所在的距离最近。 透镜定位构件将物镜调整到合适的聚焦位置,在该对准位置物镜具有跨越由自动被摄体距离检测装置检测到的最近预定距离的景深。 另一个透镜定位构件将物镜调整到聚焦位置,在聚焦位置中,物镜将无限远地聚焦在诸如景观的被摄物体上,与自动被摄体距离检测装置检测到的距离无关。 在按下快门按钮之前,当旨在在无限远拍摄被摄体时,后一个物镜定位构件可外部操作。
