Otherwise the aperture displays will show only the number of stops ( , with maximum aperture displayed as ) and the f/-number must be read from the lens aperture ring. Exposure Warning If the camera is unable to produce the correct exposure at the selected aperture, the electronic analog exposure display ( 91) in the viewfinder will show the amount of under- or over-exposure and one of the following indicators will be displayed in the control panel and viewfinder shutter-speed displays: Indicator Description Subject too bright. Choose smaller aperture (larger f/-number) or lower sensitivity (ISO equivalency; 50), or use optional Neutral Density (ND) filter. Subject too dark. Choose larger aperture (smaller f/-number) or higher sensitivity (ISO equivalency; 50), or use optional Speedlight. Aperture Lock Aperture can be locked at the selected setting ( 92). b3-EV Step ( 181) This option controls whether changes to shutter speed and aperture are made in increments equivalent to 1/3 EV (the default setting), ½ EV, or 1 EV. f5-Command Dials ( 198) Command dials > Change Main/Sub and Command dials > Aperture setting control whether aperture is assigned with the main command dial, the sub-command dial, or the lens aperture ring.
