Depth-of-Field PreviewN
 
If the “30"” shutter speed blinks, it indicates 
underexposure.
Turn the <6> dial to set a larger aperture (smaller 
f/number) until the blinking stops or set a higher ISO 
speed.
 
If the “8000” shutter speed blinks, it indicates 
overexposure.
Turn the <6> dial to set a smaller aperture (larger 
f/number) until the blinking stops or set a lower ISO 
speed.
Aperture Display
The larger the f/number, the smaller the aperture opening will be. The 
apertures displayed will differ depending on the lens. If no lens is attached to 
the camera, “00” will be displayed for the aperture.
 
A higher f/number will make more of the foreground and background fall 
within acceptable focus. However, the viewfinder will look darker.
 
If the depth of field is difficult to discern, hold down the depth-of-field 
preview button while turning the <6> dial.
 
The exposure will be locked (AE lock) while the depth-of-field preview 
button is pressed.
