4. Operating modes of the mecablitz

4.1 TTL flash mode

The TTL flash mode is a very simple way to achie-
ve excellent flash shots. In this mode exposure
readings are taken by a sensor built into the
camera. which measures the light reaching the
film through the camera lens. The electronic con-
trol circuit within the camera transmits a stop sig-
nal to the mecablitz 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 influencing cor-
rect 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 the flash, the
camera's electronic system automatically deter-
mines the correct amount of flash light required.
For the maximim flash range please observe the
distance given in the LC display of the mecablitz
(see 5.4). If flash exposure was correct, the LC
display of the mecablitz indicates „o.k." for about
3 sec. (see 4.1.3).
The TTL flash mode is supported by all camera
modes (e.g. Green Full Auto Mode, Program P,
Aperture Priority Mode „Av", Shutter Priority
Mode „Tv", Programmed Image Control Modes,
Manual Mode „M", etc.).
To test the TTL function a film must be loa-
ded in the camera. When selecting the film
please check whether limits regarding
maximum film speed or ISO value (e.g.
maximum ISO 1000) are applicable to the
given camera when in TTL mode (refer to
the camera's operating instructions)!
Setting procedure for TTL mode
With some cameras the TTL mode is auto-
matically activated on the mecablitz when
in the green full auto mode or programmed
image control mode!
• Turn on the mecablitz by its main switch.
