发明名称 Camera with means for coordinating aperture and focus adjustments
摘要 A camera is provided that has an automatic focus detector and a manually operable focus adjustment device, in which the focus adjustment device can be set at a predetermined position or range falling outside of an ordinary focus adjusting range. At the same time a coordinating device is provided which functions to secure an appropriate depth of field (or a hyper focal range) by coordinating the focus adjustment and the exposure aperture adjustment when the focus adjustment device is set at the predetermined position or range. Thus even in a case when the focus detector can not function effectively, practically satisfactory photographing can be done by the action of the coordinating device.
