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.
The depth-of-field effect can be clearly seen on the Live View image as
you change the aperture and press the depth-of-field preview button
(p.132).
The exposure will be locked (AE lock) while the depth-of-field preview
button is pressed.
