Fuji has formerly announced the M-mount adapter first seen at CES earlier in the year. The new mount allows the fitment of Leica M series lenses (or any lens using a M-mount: Zeiss ZM, Voigtlander etc) on the X-Pro1. T
According to the press release; 'the M Mount Adapter features an array of electronic connections that automatically pass information to the X-Pro1 body based on pre-registered lens profiles. With firmware version 1.10 or later, this information is transmitted by pressing the Function button on the side of the adapter, which allows users to access the Mount Adapter Settings menu on the rear LCD'...To ensure the Fujifilm M Mount Adapter delivers optimum results, users can create and fine tune lens profiles through the X-Pro1’s Mount Adapter Settings menu. This menu allows X-Pro1 users to profile up to six lenses. There are four presets for 21mm, 24mm, 28mm and 35mm lenses, plus two optional settings for additional optics.'
The new mount adapter will be avilable in June for $199.95
Fuji has posted a list of compatible lenses here*, as well as a useful product overview here. Kudos to Fuji for doing this, as the Fuji X-Pro1 is a viable alternative to the Leica M8/9 providing the raw file coversion support can be implemented satisfacitorily (in Lightroom, ideally, but I don't mind Aperture, DxO or C1).
