■AF Spotbeam
The AF540FGZ features a built-in red spotbeam
projector to assist the autofocus system in dim light and
low-contrast conditions. When using the flash with
autofocus camera in dark conditions, the spotbeam will
be projected automatically depending on the ambient
lighting conditions. This function is activated only when
the camera is set to autofocus. By setting the flash
mode to (SB), the AF540FGZ can be used exclusively
as a focusing aid in dim light.

the shutter release button and press it halfway
down again to recompose the picture.

hot shoe.

aid.
