f: Aperture-Priority AE
Press the depth-of-field preview button
to stop down the lens to the current
aperture setting. You can check the
depth of field (range of acceptable focus)
through the viewfinder.
Depth-of-Field Preview
If the “30"” shutter speed blinks, it indicates
underexposure.
Turn the <6> dial to set a larger aperture
(lower f/number) until the shutter speed
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 (higher f/number) until the shutter
speed blinking stops or set a lower ISO
speed.
Aperture Display
The higher 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 depth of field can be
clearly seen with the Live View image (p.126).
The exposure will be locked (AE lock) while the depth-of-field preview
button is pressed.
