High-Speed Sync
High Speed Sync (FP flash) enables the flash to synchronize with all camera shutter
speeds. This is convenient when you want to use aperture priority for fill-flash portraits.
Press Function Button 2 <SYNC> so that
< > is displayed.
Check that < > is displayed in the
viewfinder.
• If you set a shutter speed that is the same as or slower than the camera’s
maximum flash sync speed, < > will not be displayed in the viewfinder.
• With high-speed sync, the faster the shutter speed the shorter the effective flash
range.
• To return to normal flash, press <SYNC> button again. Then < > will disappear.
• Multi flash mode cannot be set in high-speed sync mode.
• Over-temperature protection may be activated after 15 consecutive high-speed
sync flashes.
Second-Curtain Sync
With a slow shutter speed, you can create a light train following the subject. The flash
fires right before the shutter closes.
M: Manual Flash
The flash output is adjustable from 1/1 full power to 1/256th power in 1/10th stop

determine the required flash output.
Press <MODE> button so
that <M> is displayed.
Press the <+/-> button and
turn the Select dial to
choose a desired flash
output amount.
Press Set button again to
confirm the setting.
