7.1 TTL-flash modes

The TTL flash modes offer a very simple method of achieving very good flash
shots. In these modes, exposure readings are taken by a sensor built into the
camera, which measures the amount of light through the camera lens
(TTL = „Through The Lens"). Here the camera automatically determines the flash
performance required for a correct exposure of the shot. The advantage of the
TTL flash modes is that all factors influencing exposure (filters, change of aper-
ture and focal length with zoom objectives, extensions for close-ups, etc.) are
automatically taken into account in adjusting the flash light.
If the shot was correctly lit, the correct exposure indi-

Please note whether there are limitations for your camera in terms of
film sensitivity for TTL flash mode (for example, ISO 64 to ISO 1000; see
camera's operating instructions)! In analogue cameras there must be a
film in the camera to test the TTL function!

Depending on the type of camera different
TTL flash modes, manual flash mode and
high-speed synchronisation HSS are availa-
ble. Therefore, data transfer between flash
unit and camera is necessary before setting
the flash mode, e.g. by actuating the shutter
release. The flash mode is set by using the
„Mode" button.
will flash „OK" for about 5 seconds (see
E-TTL- and E-TTL-II - flash mode
E-TTL and E-TTL-II flash modes are digital flash modes based on the further
development of the TTL flash mode for analogue cameras. During shooting, the
flash unit emits an almost imperceptible metering preflash prior to the actual
exposure. The light reflected by the metering preflash is evaluated by the
camera. The camera adjusts the subsequent flash exposure to the photographic
situation according to the evaluation (see the camera operating manual for
more details).
Setting procedure
TTL
• Press „Mode" until „E " flashes in the
display. The flash unit automatically sets either ETTL
or E-TTL II flash mode depending
on the camera type.
A distinction between E-TTL and E-TTL II is not made in the flash unitís display or
in this manual.
The setting takes effect immediately.
After about 5 seconds the display stops flashing and the setting is saved auto-

matically. „E " appears in the display.
