KANI Square Filter Holder for SIGMA 14mm F1.8 DG HSM - 150mm Width / Sigma Square Lens Filter The included items are as shown in the photos. I personally think it's in good condition, but since there are individual differences, I've marked it as having some scratches and dirt. Please make your judgment based on the photos. This product is a set consisting of a filter holder outer frame that can use 150mm wide square filters and a holder adapter for use with the SIGMA 14mm F1.8 DG HSM. It is made of precision-machined aluminum and features high-precision fitting and a robust design. By combining the filter holder outer frame of this product with a separately sold 150mm holder adapter ring, it should be usable with other lenses as well, so please check.
