Auto Focus Assist Beam
In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will
automatically light on to make it easier for autofocus. The beam will light up only when autofocus
is difficult and get out as soon as the autofocus becomes correct.
If you want to turn off the auto focus assist beam, set the “AF” to “OFF” on the C.Fn settings.

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before
illuminating the subject. This can soften shadows behind the subject for a more
natural-looking shot. This is called bounce flash.
If you find the auto focus assist beam does not light up, this is because the camera
has got a correct autofocus.
