Quantum's TTL adapters for FreeWire wireless transceivers let your camera control flash exposure without wires. For location portraiture (beach, desert, park, etc.) use wireless TTL when photographing subjects at longer distances, when TTL cables are not practical. For commercial photography mount a Qflash in a light box and shoot wireless TTL for camera controlled soft lighting. Quantum's wireless TTL adapters work with both Qflash T & Qflash X series.
The Quantum FW53N attaches to the bottom of the FreeXWire and fits into the hot shoe of a Canon camera, to provide TTL remote operation with a Qflash.
