Purchased on April 17th. Ultimately, I didn't attach it to my lens. Returns are not possible. I'll try selling it on Mercari. The purchase price was 55,000 yen. The Canon Extender EF 2x III provides 2x magnification and comes with a lens case. - Model Name: Extender EF 2x III - Included Items: Lens case - Magnification: 2x - Condition: Unused (with bag) Thank you for viewing.
