SIGMA 10-18mm F2.8 DC DN Contemporary for Canon RF. I purchased this used online from a camera specialty store a few months ago. I haven't used it much, so I'm selling it to organize my equipment. It's for Canon RF mount. There is no outer box. Everything in the photos is included. The exterior appears to have no major scratches or stains. The lens surface is also clear. The rear cap is slightly dirty. Would anyone interested like to have it? I am also listing it on other sites, so please understand that I may suddenly remove the listing. Thank you.
