AF-Assist Beam
¡The AF-assist beam will sometimes emit when the
shutter button is pressed halfway to assist focusing in
certain conditions, i.e. dark conditions.
¡The AF-assist beam can be tur ned off (p. 132).
If animals are your subject, turn off the beam when
shooting in the dark to avoid startling them (this may
however, make it more difficult for the camera to focus).
