    • An image sensing apparatus is provided with an aperture unit (104), an image sensor (106) that converts light beams entering through a photographing lens (103) and the aperture unit into electrical signals, and a display unit (107), including an electronic viewfinder mode to continuously display on the display unit images based on the electrical signals obtained by the image sensor. The image sensing apparatus has a control unit (135) that causes the aperture unit to stop down, when there is an instruction to display on the display unit an image other than the image based on the electrical signals obtained by the image sensor while in the electronic viewfinder mode.
