Though this has been shown off before, Fujifilm is now coming out to everyone about their Leica M to X Mount adapter. Being officially announced today, it seems to be very much alike to other adapters. I’d go even as far to say that this looks like the Dot Line adapter that I use for Micro Four Thirds.
The design consists of an aluminum mount for the body, stainless steel for the lens, and an aluminum central tube. All in all, the adapter from Fuji will maintain the 27.8mm needed to be from the sensor. With firmware 1.10, the adapter will also recognize the lens mounted and transmit necessary information to the camera. That means that the framelines you see in the viewfinder will correspond to the lens used. It will also transmit distortion control information, vignetting correction and color shading correction.
You can expect it in June for $199.99.
