Metabones EF-E mount with strap This adapter allows you to mount EF lenses on E-mount cameras. It has electronic contacts, but not all lenses will have full electronic functionality. I used this adapter until about three years ago, but haven't used it since. I have not tested its functionality at the time of listing. Therefore, it is sold as-is, with no guarantee of operation and no returns accepted. A Ninja Strap is attached. I have lost the hex wrench and am unable to remove it, so I will include it as a bonus. The strap has some dust and a little mold, so I recommend that those who are not planning to clean it dispose of it.
