By default, the AF points light up in red when focus is achieved in low-
light conditions. In Creative Zone modes, you can set whether to have
the AF points light up in red when focus is achieved (p.424).
Under low-light conditions, when you press the shutter button halfway,
the built-in flash may fire a brief burst of flashes. This illuminates the
subject to help autofocusing.
