The K&F 3-in-1 Lens Filter ND2–32 (1–5 Stops) Variable ND + CPL Circular Polarizing + Black Diffusion 1/4 Nano-C is a multifunctional hybrid filter designed for DSLR and mirrorless camera lenses. Combining three essential effects in a single unit—variable neutral density, circular polarization, and black diffusion—it offers enhanced creative control for photography and videography.
The variable ND (ND2–ND32 / 1–5 stops) function allows precise exposure control in bright environments, enabling smooth motion blur, controlled shutter speeds, and wide aperture shooting even under strong sunlight. The CPL polarizing layer reduces reflections from water, glass, and non-metal surfaces while enhancing contrast and color saturation. The black diffusion 1/4 layer softens highlights and creates a cinematic glow effect, ideal for portrait and film-style imaging.
Built with high-definition optical glass and advanced Nano-C multi-coating technology, the filter minimizes flare, ghosting, and color distortion while maintaining strong image clarity. The multi-coated surface also improves resistance to water, oil, dust, and scratches for reliable outdoor use.
Its precision-engineered rotating frame allows smooth adjustment between ND, CPL, and diffusion effects, while the slim aluminum alloy construction reduces vignetting and ensures compatibility with wide-angle lenses.
