Viltrox EF-FX2

Viltrox EF-FX2 Auto Focus Lens Adapter for Canon EF Mount Lens to Fuji X-Mount. Viltrox EF-FX2 mount adapter is designed to allow Canon EF-mount series lenses to Fuji X-Mount mirrorless cameras. Focal length is multiplied by 0.71 based on the original (equivalent focal length = focal length x 0.71), which helps enlarge 1 level aperture.

In addition to mechanically adapting Canon EF lenses to the X-Mount, it also reduces the focal length (x 0.71) and increases the lens aperture by approx. 3 EV. The electronic contacts mediate autofocus and aperture commands, as well as EXIF metadata; a USB port is used to upgrade the FW. The underside of the adapter hosts a 1/4" thread for mounting elements/stat. Weight 145 g, dimensions 68 x 27 mm.

Not compatible with Fuji X-Pro 3.
