¡ 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 attahed 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 1/200 sec., it will be set automatically to 1/200 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.74)
