Manual partial light output levels

Partial light output can be set in manual flash
mode .

Setting procedure

• Press the sensor button for partial light out-

put on the touch display as many times as
it takes for the partial light output display
to appear.

• Press sensor buttons

on the

touch display and set the desired partial
light output to 1/1, 1/2, 1/8 or 1/128.

• Press the sensor button on the touch dis-

play for the selected partial light output.

The setting is immediately effective and
automatically saved.

The distance display is adjusted to the partial
light output automatically (see 5.2).

6.4 Automatic high-speed synchronisa-

tion (HSS)

Various cameras support automatic high-
speed synchronisation (see the camera’s
operating instructions). This flash mode
makes it possible to use a flash unit even
with shutter speeds that are faster than the
flash sync speed.

Interesting results may by achieved in this
mode when, for example, a wide open aper-
ture (e.g., f/2.0) is used to limit the depth of
field in portrait shots taken in very bright
ambient light. The flash unit supports high-
speed synchronisation in

flash

mode.

For physical reasons, however, high-speed
synchronisation significantly reduces the
number and the maximum flash range.

Be sure to note, therefore, the flash range on
the display of the flash unit. High-speed syn-
chronisation is activated automatically if a
shutter speed faster than the flash sync
speed is set on the camera, whether manual-
ly or automatically by the exposure program.

Note that in the case of high speed synchro-
nisation the guide number of the flash unit
also depends on the shutter speed.

The faster the shutter speed, the lower the
guide number!
