ABSTRACT:
A camera that has the ability to direct the object light simultaneously to the imaging position and a first light receiving device and a second light receiving device that are arranged in places other than the imaging position (for example, an optical focus detection system and a monitor device of the object image) is disclosed. A first light dividing device is positioned in the light optical path of the light that is transmitted through the optical image forming system and reflects a portion of the light received and transmits another portion. A second light dividing device reflects a portion of the light that is reflected at the first light dividing device and transmits another portion. The light that is transmitted through the first light dividing device is directed to a primary imaging position. One of either the reflected light or the transmitted light of the second light dividing device is directed to the optical focus detection system, while the other one is directed to the monitor device. Additionally, an additional image is superimposed at a specified position on the subject image that is observed in the monitor device.
