Hight-Speed Sync
Hight 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.
• With high-speed sync, the faster the shutter speed, the shorter the effective flash
range.
• Multi flash mode cannot be set in hight-speed sync mode.
• Over-temperature protection may be activated after 20 consecutive high-speed
sync flashes.
