The Quantum D23WR 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 Canon cameras.
Provides pre-flash metering and E-TTL II (where supported) with the Canon Digital 1D Mark III, 5D, 10D, D30, D60, 20D,EOS 1D series (all models), Digital Rebel, and Kodak Pro SLR/c cameras. Full TTL with Canon EOS1, 1n, 1nRS, 1v, EOS3, 10, 10S, 600 series, 700, 750, 850, 1000, 1000F, EOS-3, A2E, A2, A5, Elan series, Rebel, Rebel S, RT, and T90.
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.
