I have a Cambo Wide DS with the 58xl and 150 lens...and I have a Phase One P25+ that I would like to mate to the camera. I'm looking for solutions. Eventually, I'll get some digitar lenses but in the mean time, according to the Cambo Wide brochures, I need this Cambo Wide Graflock H1 interface (WDS-507) to interface my back to my camera. I could also use another rotating back (WDS-504 with ground glass removed) to create a dedicated interface with the Graphlock. I've attached a picture of the hardware that I'm trying to find.

I'm also interested in purchasing Cambo Wide DS Digitar lenses....

Any assistance would be useful. I believe I'm on the right track to get this system working. Will I need to shim to get it to critical focus?

Thank you
