Nothing new in this really. Those Visoflex adapters have been on ebay for a long time, for all the main focal-plane shutter MF cameras (P67, Hassy V 2*, P645, M645), and 35mm format (D)SLRs.
I looked at the Leica lenses but nothing tempted me; they are slow and overpriced in comparison to my Mamiya 645 glass.
