摘要：
In the camera disclosed, a control circuit responds to a focus detecting circuit to energize first display portions to produce a first mark representing the detected distance, and responds to a setting arrangement to energize other display portions to produce a second different mark representing a set distance. According to an embodiment, the control circuit displays a third mark when the first and second marks coincide.
