20mm wide-angle lens for Canon. The exterior has no major scratches and I think it's in relatively good condition. It hasn't been used much and has mostly been stored in a dehumidified storage box. The optics are clear with no haze or fungus. I think there's very little dust inside the lens. I have confirmed the operation, but please understand that it has been stored by a non-professional. The included accessories are only those shown in the photos.
