Depth of Field
The depth-of-field indicators on the lens show the
approximate depth of field (see page 172 for more
information). If the camera offers depth-of-field preview (stop
down), depth of field can also be previewed in the viewfinder.

Aperture is adjusted using camera controls.
Built-in Flash Units
When using the built-in flash on cameras equipped with a
built-in flash unit, shoot at ranges of 0.6 m (2 ft) or more and
remove the lens hood to prevent vignetting (shadows
created where the end of the lens obscures the built-in flash).
The Lens Hood
The lens hoods protect the lens and block stray light that
would otherwise cause flare or ghosting.
Align the lens hood lock mark (—{)
with the lens hood mounting mark (
●)
on the lens (e).
When attaching or removing the hood, hold it near the
symbol on its base and avoid gripping it too tightly.
Vignetting may occur if the hood is not correctly attached.
The hood can be reversed and mounted on the lens when
not in use. When the hood is reversed, it can be attached and
removed by rotating it while holding it near the lock mark
(—{).
