Aperture-Priority AE ooIf the "30"" shutter speed blinks, it indicates underexposure. Turn the dial to set a larger aperture (lower f/number) until the shutter speed blinking stops or set a higher ISO speed. ooIf the "1/4000" shutter speed blinks, it indicates overexposure. Turn the dial to set a smaller aperture (higher f/number) until the shutter speed blinking stops or set a lower ISO speed. Aperture Value Display ooThe higher the f/number, the smaller the aperture opening will be. The f/number displayed varies depending on the lens. If no lens is attached to the camera, "F00" will be displayed for the aperture. Depth-of-Field PreviewM Press the button you have assigned to depth-of-field preview (using [8C. Fn III-5: Customize buttons], (=537)) to stop down the lens to the current aperture setting and check the area in focus (depth of field). ooThe larger the aperture value, the wider the area in focus, from the foreground to the background. ooExposure is locked (AE lock) as you hold down the button assigned to depthof-field preview. 101
