Purchased from Bic Camera on July 9, 2025. Upon opening the box, I realized it was not compatible with my camera, so I put it back in the box and stored it. It has only been opened to check the fit and is unused. I am selling it because I have no plans to use it in the future. Regarding the size description, I selected Canon EF mount because RF was not available. This is an RF mount lens. Please reconfirm the details in the photos.
