The Nikon-specific FlexTT5 radios work within the Nikon i-TTL / CLS system.
Use the FlexTT5 Transceiver to control single or multiple off-camera lights.
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 manual flash or remote cameras.
