Shooting-The Basics AF-assist Beam z The AF-assist Beam will sometimes emit when the shutter button is 2 pressed halfway to assist focusing in certain conditions, e.g., dark conditions. z The AF-assist Beam can be turned off (p. 77). For example, if animals are your subject, turn off the beam when shooting in the dark to avoid startling them. However, please keep in mind the following facts. - Turning the AF-assist Beam off when shooting in dark places may make it more difficult for the camera to focus. - Even when the AF-assist beam is turned off, the red-eye reduction lamp fires when [Red-eye] is set to [On].
