TELE PLUS conversion lens that doubles the focal length. There are scratches on the exterior (see photo 3). Regarding the lens, there is some minor dust inside from use, but there are no foreign objects that would affect the photos, and I believe there are no problems with its use. Please purchase only if you understand this. - Model Name: 2X TELEPLUS MC7 - Compatibility: For Canon - Brand: TELE PLUS - Features: 2x focal length extension
