The Quantum D10W QTTL module used with the FreeXwire FW9T Transmitter will allow full wireless operation of the Qflash T5d flash model, when combined with a wireless receiver and used with the Olympus E1, E20, and E300 cameras.
QTTL adapters can offset Qflash output between -3 to +2 stops (in 1/3 steps) in relation to the f/number setting on the camera. Even if the camera doesn't support fill/flash ratio, the QTTL ratio setting tracks the camera aperture as it changes, providing automatic fill/flash ratio.
