This achievement goes beyond numbers—it’s strong proof that K&F CONCEPT’s innovation in optics and product usability has earned the recognition of creators worldwide.

As visual content creation accelerates and diversifies, photographers and videographers today face a key challenge: adapting swiftly and precisely to changing lighting conditions without disrupting creative flow.

What they need isn’t more gear—it’s smarter gear.

The K&F CONCEPT Nano-X CPL-VND-Black Mist 3 in1 Filter is crafted precisely for that need.

One Filter. Endless Possibilities.

Whether you're shooting portraits under harsh afternoon sunlight，capturing time-lapse cityscapes at dusk, or filming products under studio lights, what once required three separate filters is now simplified into one. A quick flick of the lever, a simple rotate of the frame—and you’re ready to roll.

This innovative filter combines three essential optical effects into one professional-grade tool:

● ND2-32 Variable ND Filter5-stop light reduction lets you shoot with wide apertures under bright light for shallow depth of field, or maintain consistent shutter speeds for video in variable lighting. It also enables long exposures in low light—perfect for turning twilight traffic into glowing motion trails.

● CPL (Circular Polarizer)：Enhance contrast and saturation in skies and foliage, darken highlights, and cut through unwanted reflections on glass and water. It effectively eliminates distracting glare, bringing out depth and clarity in landscapes.

● 1/4 Black Mist Filter：The built-in 1/4 Black Mist adds soft halation to highlights, smooths skin tones,—delivering a cinematic, organic look inspired by analog film. Ideal for portraits and emotional storytelling

Engineered for Precision, Designed for Professionals

This 3-in-1 filter isn’t just about merging functionality—it’s about smart, intuitive design for creators.

An innovative orange lever with a locking mechanism—K&F CONCEPT’s answer to dual-filter control confusion.

● The signature orange locking lever precisely adjusts the ND setting (ND2–ND32) when loosened.

● Once set, simply tighten the lever and rotate the outer ring to adjust the CPL independently.

No need for constant readjustments—this mechanism keeps your setup smooth, your focus sharp, and your shoot uninterrupted

Constructed with 28-layer multi-coated AGC Japanese optical glass, it delivers outstanding clarity and durability. The coatings provide anti-glare, waterproof, oil-resistant, and scratch-proof protection, making it reliable across diverse and demanding environments.
