About HOLOGRAM AF
"HOLOGRAM AF (Auto-Focus)," an application
of laser holograms, is a new AF optical system
that enables still image shooting in dark places.
Having gentler radiation than conventional high-
brightness LEDs or lamps, the system satisfies
Laser Class 1 (*) specification and thus maintains
higher safety for human eyes.
No safety problems will be caused by directly
looking 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 image residual and
dazzling, that you encounter after looking into a
flashlight.
* HOLOGRAM AF satisfies Class 1(time base 30
000 seconds), specified in all of JIS (Japan),
IEC(EU), and FDA(US) industry standards.
Complying with these standards identifies the
laser product to be safe, under a condition that
a human looks at the laser light either directly
or even through a lens for 30 000 seconds.
