Rayqual made an announcement on their website yesterday they they will soon be shipping an M-Mount adapter for the Fuji X-Pro 1. So they will join Kipon and at some point Fuji with an adapter. I assume when the product is released it will show up on eBay. A quick search shows that the Rayqual adapters are a little higher in price than the Kipon alternatives. You can look through the announcement here. I have translated it from the Japanese. Along with the M-Mount there will also be a number of other adapters available as well. All of the usuals: Nikon, Canon, Leica M, Yashikon, Pentax, OM and Leica R. I don’t think I will be purchasing any of these adapters since I already own the Kipon M-Mount and have had marginal results with it. Maybe there is something Rayqual or Fuji can do to help the lack of sharpness on the edges of the wide-angle lenses, but I’m skeptical.
