of this sync mode.
●
As can be seen in the table on page 84, as the
shutter speed becomes faster, the guide number
becomes smaller. Accordingly, it should be
noted that the distance for taking pictures would
become shorter.
Procedure
Turn on the camera. Set the exposure mode to a
mode other than the Programmed AE.
Attach the flash unit to the camera’s hot shoe and
turn it on.
Set the sync mode switch to high-speed sync
(
).
● The flash will be set to high-speed sync mode
and (
) will be shown on the LCD panel only
when the shutter speed exceeds X-sync speed.
To set exposure compensation, press the select
button (S) so that (0.0) blinks. Then turn the
adjustment dial to set the exposure
compensation amount. Press the select button
(S) again to stop the blinking.
The exposure compensation amount can be set
from +1.0 to -3.0 steps in 0.5-step increments.
(Refer to page 18.)

differs according to your camera and lens. Refer
to page 21.)
