This EF-FX Pro III Autofocus Adapter from Fringer allows you to use a Canon EF or EF-S mount lens on your FUJIFILM X-mount camera. It features native support for in-camera aperture adjustment and 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. This upgraded version features comprehensible weather sealing, enabling its use under almost any conditions.

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.
