Recording images with the
hologram AF
The hologram AF is fill light to focus more
easily on a subject in dark surroundings.
appears on the screen and the hologram
AF emits red light when the shutter button
is pressed halfway until the focus is locked.
When not using this function, set
[Hologram AF] to [Off] in the SET UP
settings (page 140).
• If hologram AF light does not reach the subject
sufficiently or the subject has weak contrast,
focus will not be achieved. (An approximate
distance of 0.5 m to 5.0 m (19
3 /
4
inches to
16 feet 4 7 /
8
inches) (W)/0.6 m to 3.5 m
(23 5 /
8
inches to 11 feet 5 7 /
8
inches) (T) is
recommended.)
• Focus is achieved as long as hologram AF light
reaches the subject, even if the light is slightly
off the center of the subject.
• When adjusting the focus manually (page 67),
the hologram AF does not function.
• If the hologram AF emitter is dirty, the
hologram AF light may be dimmed and focus
may not be achieved. In this case, wipe the
hologram AF emitter with a dry cloth.
• Do not block the hologram AF emitter during
recording.
• The AF range finder frame is not displayed. AF
range finder frame indicator flashes and the
centrally-located subject has priority to focus
on.
• When you attach the supplied lens hood to the
camera, the hologram AF light is blocked.
• The hologram AF does not function when
[SCN] (Scene) is set to
(Twilight mode) or
(Landscape mode).
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
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.
