Hi.
I have a Cambo WDS, and I use it with a Betterlight, 4x5 film, 120 film and soon, an MFDB. For the MFDB, all you need is the adapter from Cambo that goes in place of the revolving back. Or you can use a Graflok adapter from any of the MFDB manufacturers. The other fittings are all the same.
Cheers,
Kumar
