Crafted from pure high-definition optical glass, this set includes two durable and versatile filters that offer variable densities of 2 to 5 stops (equivalent to ND4-ND32) and 6 to 9 stops (equivalent to ND64-ND512). This range of light control makes these filters an all-day solution, perfect for everything from overcast conditions to bright, sunny days. Each filter in this pack is multi-coated with 18 layers, ensuring a high-quality filmmaking experience by reducing lens flare and ghosting.

The hard stop feature of these filters eliminates any chance of cross-polarization, ensuring consistent and accurate color representation in all your shots. Plus, with zero vignetting on lenses 16mm and above, you can capture wide-angle scenes without any darkening at the corners. Designed for efficiency and versatility, these 67mm circular filters are compatible with a wide variety of lenses, making them a valuable tool for all your photography and videography needs.
