5.6 TTL flash mode

The mecablitz is only suitable for the TTL flash mode.

The TTL flash mode is a very simple way to achieve excellent

flash shots. In this mode exposure readings are taken by a

sensor built into the camera which measures the light reach-

ing the film through the camera lens (TTL). The electronic con-

trol circuit within the camera transmits a stop signal to the

mecablitz as soon as the film has been exposed by the cor-

rect amount of light, thereby instantly interrupting the flash.

The advantage of this flash mode is that all factors in-

fluencing correct exposure of the film (filters, change of aper-

ture and focal length with zoom lenses, extensions for close-

ups, etc.) are automatically taken into account. You need not

worry about setting the flash, the camera’s electronic system

automatically determines the correct amount of flash light

required.

If flash exposure was correct, the “o.k.” exposure confirma-

tion lights up.

The TTL flash mode is supported by all camera modes (e.g.

Full Auto Mode, Program P, Aperture Priority Mode “Av” or

“A”, Shutter Priority Mode “Tv” or “S”, Programmed Image

Control Modes, Manual Mode “M”, etc.).

To test the TTL function a film must be loaded in the

camera. When selecting the film please check whether

limits regarding maximum film speed are applicable to

the given camera when in TTL mode (refer to the

camera’s operating instructions).
