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.

1 Switch on the mecablitz with the main switch.

2 Depress the Mode button repeatedly until TTL flashes 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
