An image pick-up apparatus capable of displaying a detected subject region in a field of view of an optical finder intelligibly, and shortening a time until achieving a focus on a subject so as to decrease a release time lag. A focus detection unit detects data concerning a focus adjustment of a subject. An indication unit indicates a focusing point selected as a target of the focus adjustment among focusing points arranged at positions in a field of view of an optical finder according to the data detected by the focus detection unit. A subject detection unit detects a region of the subject using a signal that is different from the signal used for the detection in the focus detection unit. A control unit controls the indication unit based on the detection result of the subject detection unit so as to indicate the focusing points surrounding the region of the subject.
