Here is something interesting! Use your EOS EF or EF-S mount lenses on your FujiFilm X-mount camera. Because there is no electrical connection and therefore no aperture control, this adapter comes with drop-in magnetic neutral density filters (ND4, ND8, ND16) to assist in controlling your exposure. It also features a helicoid to provide macro focus or correction of back focus effects. A novel solution if you want to explore the vast lineup of Canon EOS lenses.
