Congratulations on your purchase of the PocketWizard FlexTT5® Wireless Photo Control System for Panasonic! You can use the FlexTT5 Transceiver to control single or multiple off-camera electronic or intelligent TTL flashes. The PocketWizard ControlTL® System takes the complex TTL data being sent through the camera’s hot shoe and digitally interprets and transmits it as a reliable radio signal. You can now place TTL or manual flashes anywhere to illuminate the scene: Around corners, out-of-sight and in bright sunlight. The FlexTT5 is compatible with any PocketWizard radio for triggering a manual flash.
