avoid overexposure.
The minimum lighting distance is approx. 10 per
cent of the maximum flash range indicated on the
LC display. Since the maximum flash range is not
indicated on the LC display when the reflector is
swivelled down, then be guided by the maximum
flash range indicated by the mecablitz when the
reflector is in its normal position!
4.4 Flash synchronisation
4.4.1 Normal synchronisation
In normal synchronisation the mecablitz is trigger-
ed at the beginning of the shutter time (1st curtain
synchronisation). Normal synchronisation is the
standard mode on all cameras, and is suitable for
most flash shots. Depending upon the given
mode, the camera is changed over to the came-
ra's sync speed, the customary ones being bet-
ween 1/30th sec. and 1/125th sec. (see the
camera's operating instructions). No settings have
to be made on the mecablitz, nor is there any dis-
play for this mode.
4.4.2 REAR - Second-curtain synchronisation
Some cameras offer the facility of second-curtain
synchronisation (REAR mode) triggering the
mecablitz by the end of the exposure time.
Second-curtain synchronisation is particularly
advantageous when using slow shutter speeds
(slower than 1/30 s) or when shooting moving
objects that have their own source of light.
Second-curtain synchronisation gives a more rea-
listic impression of movement because the light
streaks behind the light source instead of building
up in front of it, as is the case when the flash is
synchronised with the 1st shutter curtain! Depend-
ing on its operating mode, the camera uses shut-
ter speeds slower than its sync speed.
The REAR function can only be used if the
mecablitz is mounted on a camera that sup-
ports this function. The camera must be
switched on to select and set this function.
The camera's shutter release must be briefly
touched so that the corresponding data can
be exchanged at least once between the
camera and the mecablitz. On some came-
ras the REAR function is not possible in cer-
tain operating modes (e.g. Green Full Auto
Mode or Programmed Image Control Mode)
so that it cannot be selected. It will then be
