The „ok“ display on the mecablitz lights up for approx. 2 sec. when flash ex-
posure was correct.
The automatic flash mode is possible with an SCA adapter and with the
SCA 301 standard foot.
Some cameras will not support the mecablitz in automatic flash mode
when an SCA adapter is used (see operating instructions for the given
camera and SCA adapter). In this case the mecablitz should be fitted
with the SCA 301 standard foot.
Setting procedure for automatic flash mode:
• Equip the mecablitz with an SCA adapter or the SCA 301 standard foot
and mount on the camera.
• Adjust the camera as described in its operating manual.
• Switch on the mecablitz with the main switch.
• Depress the Mode button repeatedly until A flashes on the display.
• Push the setting disk in the direction of the arrow for storage. The selected
operating mode will be automatically stored after approx. 5 seconds if the
setting disk is not pressed. The A icon will stop flashing and remain perma-
nent after storage.
• If the mecablitz is used with an SCA 3xx2 adapter and a camera that
automatically transmits the data for ISO film speed, zoom reflector position
and aperture, then no further settings are required. The mecablitz will
automatically adjust itself in conformity with the transmitted camera data.
When the mecablitz is operated with a camera that transmits data to
the mecablitz, it can happen that the ISO film speed will not be dis-
played (depends on the camera type); see operating instructions for
the SCA adapter. It may then be impossible to change the ISO film
speed and aperture setting!

Automatic flash mode with an SCA 300 adapter or the SCA 301 standard
foot:
In this case ISO film speed, zoom reflector position and aperture must be
manually set on the mecablitz. This is indispensable for correct flash expo-
sure because the mecablitz automatically controls the light on the basis of
these data.
Tip:
If you are using a zoom lens and do not constantly need the full power and
maximum flash range of the mecablitz, you can leave the zoom reflector at
the shortest focal length position of the zoom lens. In this manner the entire
subject will be uniformly illuminated, thereby eliminating the need to con-
stantly adapt the zoom reflector position to the given focal length.
Example:
Let us assume that you are using a 28 mm – 80 mm zoom lens. In this case
you set the zoom reflector to position 28 mm!
The subject should be located within about 40 % and 70 % of the dis-
tance range indicated on the mecablitz LC display. This gives the elec-
tronic system sufficient leeway for compensation.
Caution with zoom lenses!
Depending on their design, zoom lenses can cause a loss of light in
the order of up to one f-stop. Moreover, the effective aperture may
vary with the focal length settings. This can be compensated by cor-
recting the aperture value on the flashgun manually or by manual
flash exposure correction (see Chapter 14.).
4.1 Sub-modes of the automatic flash mode
Different sub-modes can be set when the mecablitz is in auto flash mode A:
• Auto-remote with address „Ad 1“
(see Chapter Metz Remote Mode)
• Auto-remote with address „Ad 2“
(see Chapter Metz Remote Mode)
