S Selecting the AF Point N
Under low-light conditions, when you press the shutter button halfway,
the built-in flash fires a brief burst of flashes. It illuminates the subject to
enable easier autofocusing.
Maximum aperture: Up to f/5.6
With all AF points, cross-type AF sensitive to both vertical and
horizontal lines is possible.
Maximum aperture: Up to f/2.8*
With the center AF point, high-precision, cross-type AF sensitive to both
vertical and horizontal lines is possible. The center AF point’s sensitivity
to vertical and horizontal lines is about twice as sensitive as the other
AF points.
The remaining eight AF points will work as cross-type points with f/5.6
and faster lenses.
* Except with the EF 28-80mm f/2.8-4L USM and EF 50mm f/2.5 Compact Macro lenses.

In Creative Zone modes when you pop-up the built-in flash with the <I>
button, the AF-assist beam will be fired when necessary.
