off the center of the subject.

About Hologram AF
"Hologram AF (Auto-Focus)" is an AF fill
light system that applies laser holograms to
enable you to shoot still images in dark
places. The Hologram AF system uses
gentler radiation than conventional high-
brightness LEDs or lamps, thus satisfying
Laser Class 1* specifications and
maintaining higher safety for human eyes.
No safety problems will be caused by
(Twilight mode) or
looking directly into the hologram AF
emitter at a close range. However, it is not
recommended to do so, because you may
experience such effects like several minutes
of residual image and dazzling, that you
encounter after looking into a flashlight.
* Hologram AF satisfies Class 1 (time base
30 000 seconds), specified in JIS (Japan), IEC
(EU), and FDA (US) industry standards.
Complying with these standards identifies the
laser product as safe, under the condition that a
human can look at the laser light either directly
or focused through a lens for 30 000 seconds.
