4.1 TTL flash mode (Fig. 5)
The TTL flash mode is a very simple way to
achieve excellent flash shots. In this mode expo-
sure 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 7.4.1). 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 (such as Program "P" (or "HYP" or "green
square"), Aperture Priority Mode "A" or "AV",
Shutter Priority Mode "Tv", Subject Program
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 maxi-
mum film speed or ISO value (e.g. maxi-
mum ISO 1000) are applicable to the given
camera when in TTL mode (refer to the
camera's operating instructions)!
