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.
