The PocketWizard MiniTT1 Radio Slave Transmitter is part of an ultra-versatile radio slave system, and is dedicated specifically to the Nikon i-TTL flash control system. It simply slides directly into the camera's hot shoe, and there are no special settings to make or modes to call up. Use the camera, on-camera flash, or flash commander controls for flash compensation, zone and ratio control. It supports single or multiple dedicated flash units.
The MiniTT1 is the ideal addition to any Nikon i-TTL flash system. It works in combination with the FlexTT5 Transceiver, and since this system works on digital radio technology, it can support i-TTL operation around corners, out-of-sight, or in bright sunlight.
