Newly released, designed for mirrorless and full frame 35mm cameras...would work flawlessly on the new M with live view or the EVF. The whole package with bellows, Schneider lens, focusing rails, and camera adapter is only €1299 (incl VAT, so likely less for those of us out of the EU). It will definitely be a purchase I consider after I get the M.
It mentions the degrees it is capable of shifting and tilting, which is enough for many still life and architectural applications...so it's not just a macro set up, though standard 35mm lenses adapted to the bellows will not focus to infinity.
