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.

Comments about Quantum Instruments D12W Wireless QTTL Adapter:
You need this if you are using a late model camera and want to get the best out of your Quantum TTL connection. Highly recommended if you don't have time to think or play with your flash due to the shooting fast pace. Fast dial-up for minus/plus adjustments, no menus or commands to play with. A blessing!
