lamp may be illuminated. It illuminates the
subject to enable easier autofocusing.
When an EF or EF-S lens is used, the focus will be locked as shooting starts,
even if you shoot continuously with Servo AF (except for STM lenses).
When you hold the camera, be sure not to obstruct the AF-assist lamp (p.48).
In <5> or <C> mode, the AF-assist lamp does not emit the AF-assist beam.
The AF-assist beam will not be emitted when [AF operation] is set to [Servo
AF].
In Creative Zone modes, the AF-assist beam will be emitted when necessary.
In movie shooting modes, the AF-assist beam will not be emitted.
Emission of the AF-assist beam makes it easier to focus at the center of the
screen.
Depending on the lens attached, the AF-assist beam may be obstructed and
the camera may not be able to focus automatically.
You can enable or disable the AF-assist beam with the [4: AF-assist beam
(LED) firing] setting under [54: Custom Functions (C.Fn)].
When using an external flash, the AF-assist beam of the flash will not be
emitted. However, if you use an EX-series Speedlite (sold separately)
equipped with an LED light, when [AF operation] is set to [One-Shot AF], the
LED light will turn on for AF-assist if necessary.
