Use the built-in flash at least 1 m/3.3 ft away from the subject. Closer distances will cause the lens barrel to partially obstruct the flash. When using the built-in flash, detach any hood attached to the lens. A lens hood will partially obstruct the flash.

A super telephoto lens or fast, large-aperture lens may partially obstruct the built-in flash coverage. In such a case, using an EX-series Speedlite (optional) is recommended.

The built-in flash’s coverage is effective with lens focal lengths as short as 17mm. If the lens is shorter than 17mm, the periphery of the flash photo will look dark.

To retract the flash, push it back down.

In the <s> <a> modes, even if you set the shutter speed to one faster than 1/250 sec., it will be set automatically to 1/250 sec.

If autofocus cannot be achieved, the AF-assist beam (small flashes fired by the built-in flash) will be fired automatically (except in the <3> <5> <7> modes). (p.78)
