For sale is a genuine Canon Mount Adapter EF-EOS M. This product consists of the following four items: 1. EF-EOS M Mount Adapter 2. F Cap 3. R Cap 4. Detachable Tripod Mount Purchased in 2023, around the same time as the M5. I bought it as a backup, as it allows the use of EF lenses, but I haven't had the opportunity to use it in two years, so I'm putting it up for sale. I only attached it two or three times indoors to check its compatibility. Of course, I haven't taken it outdoors. Therefore, I believe it's in almost new condition. However, it is an item that has been in someone's hands once. Please consider and purchase only if you don't mind. Thank you for reading to the end.
