FLASH SYNCHRONIZATION

AUTOMATIC FLASH SYNCHRONIZATION TIME
CONTROL
Depending on the camera type and camera mode, the
shutter speed is switched to flash synchronization
time when the flash is ready (see camera manual).
Shutter speeds that are faster than the flash
synchronization time cannot be set or are switched to
flash synchronization time. Various cameras have a
synchronization time rang , e.g.
camera manual). The synchronization time that the
camera then uses depends on the camera mode, the
ambient light and the lens focal length used.
Shutter speeds that are slower than the flash
synchronization time can be used, depending on the
camera mode and the flash synchronization selected.
There is no automatic flash synchronization time
control in cameras with central locking and high-
speed synchronization (see p. 63). As a result, the
flash can be used at all shutter speeds. If you need
the full light output of the flash unit, do not choose a
shutter speed faster than

NORMAL SYNCHRONIZATION

In normal synchronization, the flash unit is fired at the
start of the exposure time. Normal synchronization is
standard operation and is carried out by all cameras.
It is suitable for most flash photographs. The camera
is switched to flash synchronization time depending
on your mode.
Times between ⁄ s and ⁄ s are usual (see camera

manual).
There is no display for this mode on the flash unit.
SLOW SYNCHRONIZATION
SLOW
With slow exposure the picture background is
SLOW
made more prominent in low ambient light. This is
achieved with camera shutter speeds that are
adapted to the ambient light. The camera automati-
cally sets shutter speeds that are longer than the
flash synchronization time (e.g. up to 30s). With some
camera types, slow synchronization is automatically
activated in certain camera programs (e.g. night
photography program, etc.) or it can be set on the
camera (see camera manual). There is no setting or
display for this mode on the flash unit.
Slow synchronization is set on the camera (see
SLOW
camera manual)!
Note:
With slow shutter speeds use a tripod to prevent
blurred shots!
