Fig. 17: Partial light output levels in the manual mode
Setting procedure for manual mode with partial light output:
• Adjust the camera in the manner described in the operating instructions.
1
Switch on the flashgun with the main switch
.
2
Adjust the operating mode selector
to
M
.
• *Press the
ISO
button
and then adjust the film speed with the
+
or
-
button
• *Press the
Zoom
button
and use the
+
or
-
button
to adjust the zoom
value that equals the focal length of the camera lens.
3
Press the
button.
4
Use the
+
or
-
button
to continuously change the flashgun’s aperture until
the required aperture appears on the LC display. Now set the same aperture
on the camera.
If an SCA 3000 adapter is used, some cameras automatically transmit
the f-number. Should this be the case, the aperture on the camera
must be changed until the required f-number appears on the LC
display of the flashgun.

Press the
P
button
, and then use the + or - button

9. Working with partial light output levels
Flash durations
The adjustable partial light output levels result in different flash durations (see
Technical Data, Table 1). The specified flash durations apply only to single flashes
in manual mode. With serial flashes (winder or stroboscopic mode) the last
flashes may have a longer duration. Flash duration in the auto and TTL modes
can also be shorter when the automatic exposure control switches off the flash at
an earlier moment.
Macrophotography (close-ups)
Parallax error can be compensated by tilting the main reflector downwards by
-5° or -13°. For this purpose pull the reflector completely out, and then tilt it
down.
With close-up photography it is important to ensure that a certain minimum
lighting distance is maintained to avoid overexposure.
For exposures with extremely short flash-to-subject distances, we advise you to
use small partial light output levels in manual mode, as described on page 31.
