摘要： A detecting apparatus for focus in a camera has a memory storing at least two independent rates indicating an aberration of a photographing lens. The memory is provided on an interchangeable photographing lens. If an optical characteristic of the focus detecting apparatus within the camera body changes from a conventional one, a suitable aberration correction rate is decided accordingly on a camera body side, thereby ensuring a high precision focus detection then forward.
