This product is a set of three ND filters (ND8, ND64, and ND1000), an adapter ring, and a filter case. I purchased it from a personal sales website. It's an imported product, and as the photos show, the box has a few wrinkles, but please purchase it if you don't mind. It comes with 67/72/77/82mm adapter rings. It's new and unopened. (About the product) This product is a set of three ND filters (ND8, ND64, and ND1000), an adapter ring, and a filter case. "SWIFT FSND" is the ultimate ND filter, integrating two innovations: "FSND (Full Spectrum ND)," the cutting-edge technology in ND filters, and NiSi's unique quick-mount system, "SWIFT." FSND absorbs light evenly across all wavelengths, from ultraviolet (UV) to infrared (IR), so there is no color cast even with high-density ND filters. In addition, the SWIFT mount allows for quick filter changes and stacking. You can use the ND filter on multiple lenses with different filter diameters via the included adapter rings. The 82mm FS ND filter comes with "67/72/77/82mm" adapter rings. FS ND filters can also be stacked with other SWIFT system filters, such as ND-VARIO and SWIFT CPL, of the same diameter.
