Sub-Modes Of Ttl Flash Mode; Automatic Flash Mode - Metz MECABLITZ 70 MZ-4 Mode D'emploi

• It is possible that ISO film speed, zoom and f-stop will not be automatically
transmitted from the camera to the mecablitz, depending upon the camera
type and SCA adapter. In this case simply set the corresponding values
manually on the mecablitz. ISO film speed and f-stop are only required for
correct distance and flash range indication on the LC display and are
therefore irrelevant for TTL flash shots. Consequently, it is not imperative to
set them.
• Zoom reflector positioning is important for the correct illumination of the
entire subject. It should therefore always be adapted to the focal length of
the lens.
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 of the zoom lens. In this manner the entire subject
will be uniformly illuminated, thereby also eliminating the need to constantly
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
k
you set the zoom reflector to position 28 mm!
If the mecablitz is used with an SCA 3xx2 adapter on a camera that
transmits data to the flash unit, it can happen that the ISO speed
rating is not displayed (depending on the camera model); see the ope-
rating instructions for the SCA adapter. It may then be impossible to
change the ISO film speed and aperture! With wide differences in
contrast, e.g. a dark object in the snow, corresponding exposure cor-
rections may be necessary in TTL mode (see Chapter 14.).

3.1 Sub-modes of TTL flash mode

Different flash sub-modes can be set when the mecablitz is in TTL mode:
The number of possible sub-modes depends on the SCA adapter and
the given camera:
• TTL-remote with address „Ad 1"
(see Chapter Metz TTL Remote Mode)
• TTL-remote with address „Ad 2"
(see Chapter Metz TTL Remote Mode)
• Matrix-controlled fill-in flash
Nikon camera; see operating instructions for the SCA adapter and the
camera).
• 3D multi-sensor fill-in flash
Nikon camera; see operating instructions for the SCA adapter and the
camera).
Setting a sub-mode of TTL flash mode:
• Depress the Mode button repeatedly until TTL flashes on the display. In the
event that TTL no longer flashes, just press the Mode button once.
• Turn the setting disk and select the required sub-mode.
• Push the setting disk in the direction of the arrow for storage. The selected
sub-mode will be automatically stored after 5 seconds if the setting disk is
not pressed. The TTL icon will stop flashing after storage.

4. Automatic flash mode

In the auto flash mode a sensor built into the mecablitz measures the light
reflected off the subject. The flash is cut off as soon as sufficient light has
been emitted for correct exposure. This eliminates the need to recalculate and
reset the aperture each time the distance is changed, provided that the sub-
ject remains within the indicated maximum flash range.
The sensor of the mecablitz must be directed at the subject, regardless of the
direction in which the main reflector is pointing. The sensor has a coverage
of 25°, and only measures during light emission by the mecablitz.
