The Quantum FreeXwire 7Q mounts directly flush onto a Qflash 4d or 5d series flash with no need for any connection cords. With the FW9T or FW10w transmitter mounted on the camera (with the FW12 Hot Shoe Adapter) it is now possible to trigger the Qflash completely wireless. Or add a D or Dw series QTTL adapter to the camera and transmit the camera's f/stop ISO and TTL exposure information to the remote Qflash 5d.
