The 55mm Circular ND64 6-Stop Lens Filter Plus+ is an essential tool for photographers seeking to enhance their images in bright lighting conditions. This professional-grade filter delivers a fixed 6-stop reduction in light entering the lens, enabling precise control over long exposures and depth of field.

The glass is treated with an advanced 20-layer nano-coating, which not only facilitates higher light transmission but also maintains a more consistent transmission curve for accurate light reduction. This meticulous coating process ensures that your images remain free from color casts, preserving the true colors of your scene.
