The Fringer EF-FX PRO II is a smart adapter for FX mount. This mount adapter allows you to attach Canon EF (EF-S) mount lenses to Fujifilm X mount cameras. It supports autofocus and automatic aperture control, just like Fujifilm's native lenses. I used it with a Sigma EF mount lens on my X-H1, but I rarely used the X-H1 itself, so it's in clean condition with no scratches. The attached photos show it mounted on the X-H1. The ring that touches the camera body is the aperture ring. In other words, any EF mount lens, including those from Sigma and Tamron, can be used (though not all). - Model Name: Fringer EF-FX PRO II - Included: Original box, front and rear caps, instruction manual (English, etc. ... no explanation needed for operation.) - Mount Type: FX Mount - Function: Smart Adapter * The camera in the attached photos is not included.
