3. TTL flash mode
The TTL flash mode is a very simple way to achieve
excellent flash shots.
The mecablitz must be fitted with a suitable SCA
adapter for TTL flash mode. TTL flash mode is
only possible with cameras supporting this
mode! The SCA 301 standard foot (only hot-shoe
contact or synch cord socket) does not permit
TTL flash mode! If the mecablitz is used in con-
junction with a camera or SCA adapter that does
not support the TTL function, then uncontrolled
full-power flashes will be fired when the shutter
release is pressed! The TTL function can only be
tested if a film has been loaded in the camera!
In TTL mode, the exposure readings are taken by a sen-
sor built into the camera. This sensor measures the light
reaching the film through the camera lens. An electronic
control circuit within the camera transmits a stop signal
to the SCA adapter (optional extra) as soon as the film
has been exposed by the correct amount of light, thereby
instantly interrupting the flash.
The advantage of this flash mode is that all factors influ-
encing correct exposure of the film (filters, change of
aperture and focal length with zoom lenses, extensions
for close-ups, etc.) are automatically taken into account.
The „ok“ display on the mecablitz lights up for approx. 3
sec. when flash exposure was correct.
An additional acoustic signal can be activated
on the mecablitz; see „12.1 Bleep function“.
Setting procedure for the TTL flash mode (Fig. 4):
• Equip the mecablitz with a suitable SCA adapter and
mount on the camera.
• Adjust the camera as described in its operating
manual.

on the display. Push the setting disk in the direction of
the arrow to store this setting. The selected operating
mode will be automatically stored after approx 5
seconds if the setting disk is not pressed. The TTL icon
will stop flashing and will be continuously displayed
after storage.
• 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
