10 Automatic flash sync
speed control
Depending on the camera model and
camera mode, the shutter speed is swit-
ched to flash sync speed when flash
readiness is reached (see the camera’s
operating instructions).
Shutter speeds cannot be set faster than
the flash sync speed, or they are swit-
ched automatically to the flash sync
speed. Various cameras have a sync
speed range, for example from 1/60 sec
to 1/250 sec (see the camera’s operating
instructions). The sync speed set by the
camera depends on the camera mode,
the ambient light, and the focal length of
the lens used.
Shutter speeds slower than the flash
sync speed can be set according to the
camera mode and the selected flash syn-
chronisation.
If a camera with a between-the-lens
shutter is used, flash sync speed is not
controlled automatically. As a result,
the flash can be used at all shutter
speeds.
11 Automatic AF measuring
beam
An AF measuring beam is not possible
with Samsung cameras.
The automatic AF measuring beam
ቯ is
activated in the flash unit by the camera
when the ambient lighting conditions
become inadequate for automatic focu-
sing. A striped pattern is projected onto
the subject which the camera can use to
focus. Depending on the camera’s acti-
vated AF sensor, the AF beam has a
range of approximately 6 m to 9 m (with a
standard 1.7/50 mm lens).
Parallax error between lens and AF mea-
suring beam m limits the close-up range
with the AF measuring beam to approxi-
mately 0.7 m to 1 m.
To activate the automatic AF measuring
beam
ቯ the camera must be set to the
„Single–AF (S)“ or „ONE SHOT“ auto-
focus mode and the flash unit must
indicate flash readiness. Some camera
models support only the camera’s
internal AF measuring beam
ቯ. In this
case, the automatic AF measuring
beam
ቯ of the flash unit is not activat-
ed (as in the case of compact cameras;
