The Adorama 40.5mm ND64 + Cpl Lens Filter Plus+ is an essential tool for photographers seeking to enhance their image quality with precision and ease. Crafted with high-quality, industry-leading German B270 Schott optical glass, this filter boasts a robust 20-layer nano-coating that not only facilitates effortless cleaning but also provides superior protection against water, oil, and scratches.Our ND64 + Cpl Filter Plus+ is designed to selectively cut out 99.9% of polarized light, effectively minimizing reflections from water, glass, and non-metallic surfaces. This results in images with increased contrast, boosted color saturation, and enhanced vibrancy, unveiling the true beauty of your subject. The neutral density aspect of the filter, with a density of 1.8 (6 stop), allows photographers to experiment with longer exposure times and wider apertures, granting more creative control over motion blur and depth of field effects, even in bright lighting conditions.
