SKU CH-QTEF-W9JJ5

  • Expands lens options for Fujifilm X-Pro1 system

Compatible Cameras and Function

The adapter is built for the Fujifilm X-Pro1 interchangeable lens camera system. It connects Leica M-mount lenses to the X-Pro1 body using an aluminium camera mount, a stainless steel lens mount and an aluminium central tube. Electronic contacts on the camera side transmit pre-registered lens profiles to the body when firmware version 1.10 or later is installed.

Who Benefits and Who Does Not

Photographers who own M-mount glass and want to use it on an X-Pro1 gain a mechanically precise link with electronic metadata support. The adapter serves no purpose for owners of other Fujifilm X-series bodies, for users of non-M lenses, or for anyone requiring autofocus or aperture control through the camera.

Flange Distance Precision

The central tube holds the lens exactly 27.8 mm from the sensor plane, matching the Leica M flange specification. This fixed distance is the single dimension that determines whether adapted lenses focus correctly to infinity and render as designed.
