K&F Concept Filtro ND Variabile Fader 77mm ND2-ND2000 Nano-X Multi-Coating

The K&F Concept Fader Variable ND Filter is a versatile tool for photographers and videographers, offering adjustable neutral density from ND2 to ND2000 (1-11 stops). Designed for 77mm lens threads, it features Nano-X multi-coating for reduced reflections and enhanced image quality. The aviation aluminum alloy frame ensures durability, while the smooth stepless rotation allows precise exposure control. Ideal for long exposures, shallow depth of field in bright light, and cinematic video.

Advantages

Eliminates the need for multiple fixed ND filters, saving weight and cost. The variable design provides seamless adjustment from subtle to extreme light reduction. Nano-X coating repels water, oil, and scratches, maintaining optical clarity. Minimal color shift and X-pattern suppression at wide angles ensure professional results.

Suitable for

• Landscape photographers requiring long exposures in daylight
