The K&F Concept Nano-X Series Variable ND & CPL 2-in-1 Filter (77mm) is a versatile filter designed for photographers and videographers who want precise exposure control and enhanced image quality without changing filters. Combining a 1 to 5-stop Variable ND filter with a Circular Polarizer (CPL), it enables you to reduce light entering the lens while simultaneously eliminating unwanted reflections from water, glass, foliage, and other non-metallic surfaces.

Constructed from premium optical glass, the filter features advanced multi-resistant coatings that are waterproof, scratch-resistant, and designed to reduce flare and ghosting while maintaining excellent color accuracy. The filter offers 0.3 to 1.5 optical density (ND2–ND32), allowing smooth exposure adjustments for slower shutter speeds, wider apertures, and cinematic video capture in bright lighting conditions.

The durable aluminum filter frame is lightweight and precision-machined for reliable performance. Its rotating ring features five clearly marked ND positions, making it easy to adjust exposure accurately while maintaining polarization control. With a 77mm rear thread and 82mm front accessory thread, the filter is compatible with a wide range of lenses and allows the use of compatible lens caps and accessories.
