The Canon Mount Adapter EF-EOS R is a high-quality adapter for connecting EF lenses to EOS R cameras. - Brand: Canon - Model Name: Mount Adapter EF-EOS R - Country of Manufacture: Made in Japan Thank you for viewing. I purchased this as a spare for my usual mount adapter, but I never used it, so I am selling it. It is a new, unused item, and comes with the original box, instruction manual, and adapter case.
