I've ordered the Nex-7 and would love to use my Voigtlander Ultron 40mm f/2 pancake with it. Photodiox makes a Pro Lens Mount Adapter for Nikon to Nex. Has anyone tried this combination on the Nex-3 or Nex-5? It seems the overall size of this combination would be reasonable given the Voigtlander's small size. Any responses would be appreciated.
