The PocketWizard MiniTT1 Radio Slave Transmitter utilizes PocketWizard’s new ControlTL firmware platform, is part of an ultra-versatile radio slave system. It simply slides directly into the camera’s hot shoe. 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 flash system. It works in combination with the FlexTT5 Transceiver, and since this system works on digital radio technology, it can support E-TTL around corners, out-of-sight, or in bright sunlight.
