1. An image pickup apparatus having a change mode in which an auto focusing adjustment value is changeable with a live view being displayed on a display unit, comprising:
a display control unit configured to perform the live view for displaying an image of an object on the display unit; a photometry unit configured to measure brightness of the object; and a control unit configured to select a program diagram corresponding to a photographing mode selected by a user from a plurality of program diagrams each for deciding an electronic shutter speed, an aperture value, and an ISO (International Organization for Standardization) value, wherein in a case where the photographing mode is shifted to the change mode, the control unit allows the live view to be performed by a predetermined program diagram irrespective of the photographing mode selected by the user, and wherein when a largest aperture value of a lens is darker than a predetermined reference value, the control unit restricts the shift to the change mode.
