TTL Flash Control
When the flashgun is switched on, it will automatically set
at TTL mode and the LC display will indicate "TTL". When
"Ready" indicator lights up, press the shutter release firmly
to shoot.
The advanced programming and computerized circuitry of
the flashgun provide correct amount of flash light output
according to the camera’s exposure measurement through
the lens (TTL). If you need to change mode, simply press
the mode selector.
For Type C flash: The ETTL indicator will light while
connected with ETTL cameras.
For Type N flash: The LC Display will show TTL, I-TTL or
BL in different way while connected to different camera
models. Please refer to the camera’s manual.
Manual Flash Mode at Full Light Output
Auto-focus "AF" Measuring Flash
The integrated "AF" red light beam of the flashgun
supports automatic focusing of auto-focus TTL cameras.
When prevailing light is insufficient for automatic focusing,
the flashgun will project a red light beam onto the object as
soon as the camera’s shutter is lightly touched. The
camera’s auto-focus system then focuses the object by
this spot of red light beam.
To use the flashgun at full light output in manual mode, the
mode selector must be set to M (Manual). A full-power
flash will be fired each time the flashgun is triggered. The
LC display automatically shows the flash-to-subject
distance required for a correct exposure. An adaptation to
individual shooting situation can be achieved by changing
the lens aperture or focal length (on the camera).
5 level "Power Ratio" of 1/1, 1/2, 1/4, 1/8 and 1/16 could
be selected by slightly tapping the Mode selector when it is
at the manual position.
