6 Flash modes
Depending on camera type or group
(see table 1), different TTL flash modes,
manual mode and remote slave mode
are available.
Flash mode can be configured via the
appropriate TTL, M or SL button.

In order to configure TTL modes and
manual mode, data transfer must take
TTL
place between the flash unit and the
camera e.g. by lightly depressing the
camera shutter.

6.1 TTL flash modes
In TTL modes, excellent flash exposure is
straight-forward. In TTL mode, flash
metering is taken care of by a sensor in
the camera. It measures reflected light
through the lens (TTL). This enables the
camera to automatically determine the
flash output required for correct exposu-
re of the shot.
The benefit of TTL flash modes is that all
factors which could influence the exposu-
re (filters, changes to aperture and focal
length for zoom objectives, extensions
for close-ups etc.) are automatically
taken into account through flash light

adjustment.
If the shot is correctly lit, the button
TTL
will light up red for 3 seconds (see 4.2).
Please check whether there are any
limitations for your camera type regar-
ding the ISO value for TTL mode (e.g.
ISO 64 – ISO 1000, see camera opera-
ting instructions).
A film must be loaded into analogue
cameras to test the TTL function.
