HyperSync & High Speed Sync (FP Flash)
®
HyperSync is set in a transmitting radio only. It is not
used in a remote FlexTT5. All receiving PocketWizard
radios, including the Plus II, etc., will trigger in sync with
HyperSync. At 1/640 and above, Standard triggers
are not sent.
NOTE: HyperSync requires a MiniTT1 or FlexTT5 as a
transmitter. A Standard transmitter like a Plus II cannot
trigger a remote FlexTT5 and achieve HyperSync.
If you are seeing Front Curtain clipping (top of frame
is dark), then your HyperSync offset should be moved
towards 0 (zero). If you are seeing Rear Curtain clipping
(bottom of frame is dark), then your HyperSync offset
should be moved away from 0 (zero).
When making adjustments, try adjusting in 30 micro-
second steps until you see some changes, then try
smaller steps to fine tune your setting. Remember to
press Set Both Configs in the Utility after every
adjustment.
For some camera and flash combinations it is not possible
to eliminate clipping, especially at the faster HyperSync
shutter speeds like 1/400 and 1/500. Use a slower
shutter speed or use 1/640 or higher and engage
FP Flash/High Speed Sync. FP Flash/High Speed Sync
is not available on shutter speeds between 1/250 and
1/640 when using ControlTL radios.
