This EF-FX Pro II Lens Mount Adapter from Fringer allows you to use a Canon EF or EF-S mount lens on a Fuji X-mount body. It features native support for in-camera aperture adjustment and for phase-detection autofocus. In addition to the in-camera aperture controls, the aperture may also be adjusted using the electronic aperture ring located on the adapter itself.

While this adapter will work with all X-mount cameras, it is especially well suited for use with cameras utilizing the X-Trans II or III CMOS sensors as the autofocus will perform more quickly and reliably on those camera models.
