KF 72mm Hybrid 3-in-1 Filter: Variable ND2-32 + CPL + Black Diffusion 1/4

On a bright coastal shoot, a filmmaker needs to cut light, kill glare off the water, and soften skin tones—all without swapping filters. This KF 72mm hybrid filter handles it in one slim ring: a variable neutral density range from ND2 to ND32, a circular polarizer, and a 1/4-strength black diffusion layer. Thread it onto any 72mm lens and rotate to dial in 1–5 stops of light reduction, deepen blue skies, and add a subtle cinematic haze to portraits or video. The double-threaded frame keeps your lens cap or hood ready, while Japanese AGC optical glass and a 28-layer nano-coating preserve sharpness and resist water, oil, and scratches.

Why choose it

Combining three essential effects in one filter saves time and bag space. The variable ND lets you shoot wide open in harsh light or achieve motion blur in video, while the CPL cuts through haze and reflections. The 1/4 black diffusion adds a gentle, flattering glow without losing detail—ideal for portraits, weddings, and narrative work. Premium glass and coatings ensure minimal color shift and long-term durability.

Ideal use cases

• Outdoor portrait sessions in bright sun
• Landscape photography with water or sky
• Videography requiring shallow depth of field
• Cinematic interviews and music videos
• Travel photography where carrying multiple filters is impractical

Good to know

The filter's double-threaded design means you can stack another filter or attach a lens cap without removing it. The ultra-slim frame reduces the chance of vignetting on wide-angle lenses. For best results, rotate the filter ring to fine-tune both the ND strength and polarization angle simultaneously.
