The Quantum D12W QTTL module used with the FreeXwire FW9T Transmitter will allow full wireless operation (i-TTL/3D Matrix) of the Qflash T5d flash model, when combined with a wireless receiver and used with Kodak Pro 14n, Pro SLR/n, Nikon N90s, F100, F5, F6, D1 & D2 series, D100, D70 & Fuji S2 & S3 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.
