I just picked up the Fujifulm M Mount Adapter a few hours ago from a local dealer and headed out for a couple quick snaps. It is clear the adapter has been built to very high tolerances.
This adapter has the added benefit of a button on the dial that triggers direct access to the manual lens options in the camera’s menu.
A few sample from a quick walk. Fuji’s X-Trans sensor and Leica’s optics seem to be a perfect match.
