Checking the Depth of Field
You can press the Depth-of-Field Preview button to
close the aperture to the current aperture setting,
and then verify the range of focus in the viewfinder.
● If the 30” shutter speed blinks, the scene
is too dark. Turn the <
> dial to reduce
the aperture value (larger aperture).
● If the 4000 shutter speed blinks, the
scene is too bright. Turn the <
> dial to
increase the aperture value (smaller
aperture).
