Sigma prime lens for Canon EF mount. I purchased it used on Mercari in January of this year. There are scratches on the lens cap, etc., but the body is still beautiful. The image quality is also excellent. Numerous dust-like particles can be seen inside the lens. I don't think it will affect the photos. However, I'm selling it as junk due to possible mold, and have lowered the price accordingly. To avoid time-wasters, I will not negotiate the price. Thank you.
