This high-quality 52 mm HD MRC filter combines a Neutral Density (ND64) and Circular Polarizer (CPL) in a single unit, allowing photographers to control exposure and reduce glare simultaneously. The ND64 component reduces light entering the lens by 6 stops, enabling longer exposure times for creative effects like motion blur in waterfalls or smooth water surfaces. The CPL layer minimizes reflections from non-metallic surfaces, enhances color saturation, and improves contrast. Multi-Resistant Coating (MRC) ensures durability, reduces ghosting and flare, and provides easy cleaning. Ideal for landscape, architectural, and outdoor photography.
