SIGMA 16mm F1.4 DC DN [E-mount] APS-C Minor scratches and dirt from use. Operation checked. While there is no noticeable dust or mold inside the lens upon visual inspection, there may be fine dust particles. I believe there are no practical problems. Please refer to the photos for the condition of the product. Manufacturer's HP https://www.sigma-global.com/jp/lenses/c017_16_14/ Thank you.
