Several forum postings say that the Camera Plate Arca-Swiss Style CP-S1, along with the Arca-Swiss Style Quick Release Clamp (F2105), provide a solid, aligned connection between NN3 MkII and a Sony Nex-5. Will these adapters also work with a Sony NEX-6?

I also read that a ring lens clamp can be made for the NN3 MkII, for about $109. Might that be a more solid connection, and is such an adapter possible?
