Detach any lens hood when shooting with the built-in flash.
If a lens hood is attached or if the subject is too close, the built-in flash
will be obstructed and the bottom of the captured image may look dark.
Do not perform flash photography when the built-in flash is held down
with your finger or not fully raised for some other reason.
If you use a super telephoto lens or large-aperture lens and the bottom of
the picture looks dark, using an external Speedlite (sold separately, p.233) is
recommended.
