72mm Black Diffusion Mist + Variable ND2-32 & CPL Filter - 3-in-1 Lens

In this review the K&F CONCEPT 72mm Black Diffusion Mist Effect 1/4 & Variable ND2-32 & Circular Polarizing Filter is evaluated for photographers and videographers who want more creative control without carrying multiple filters. The bottom line: this single, well-built 3-in-1 filter combines a soft diffusion mist, a continuously adjustable neutral density range and a circular polarizer to reduce reflections and boost color, making it a useful tool for portrait softening, landscape saturation and run-and-gun video where changing glass quickly is impractical.

Key Features

• 3 Functions in 1: Combines diffusion mist, variable ND and CPL into a single unit so the user can soften highlights, control exposure and cut reflections without swapping filters.
• Variable ND2-32 (1-5 stops): An infinitely rotating ND range supports precise light reduction for moderate exposure control in bright conditions and avoids abrupt jumps between stops.
• No X cross design: The self-locking frame allows smooth rotation across the ND range and is built to prevent the black cross artifacts that can appear on some variable NDs.
• Soft highlight flares and lowered contrast: The 1/4 diffusion section softens skin texture and produces a filmic, dreamlike look ideal for portraits and subject-focused video.
• Circular polarizer effect: Reduces reflections from water and glass and increases saturation and contrast in skies and foliage for more vivid landscape shots.
• 18 multi-coatings: Coatings on the glass help reduce flare and maintain image quality while combining multiple filter effects in one piece of glass.

Who It's For

The filter is best for hybrid shooters who need flexible creative effects without switching glass frequently, such as portrait and landscape photographers who want a soft diffusion and the ability to deepen skies or cut reflections. Videographers working in run-and-gun situations will also appreciate the convenience of a single filter that softens highlights and controls exposure.

Those who should look elsewhere include professionals who need extreme ND ranges for long exposures or those who require fully removable diffusion for very sharp images; a single-piece 3-in-1 will not replace a dedicated heavy ND or a full suite of specialist diffusion filters for every situation.

Pros & Cons

Pros

• High perceived build quality and a solid rotating mechanism make adjustments feel reliable in the field.
• The combination of diffusion, variable ND and CPL reduces the need to carry multiple filters for many shooting scenarios.
• Effective softening of skin and highlight blooms creates a pleasing, filmic aesthetic for portraits and video.
• The CPL increases color saturation and contrast in skies and water without additional attachments.

Cons

• Variable ND range is moderate (1-5 stops); it is not suitable for extreme long exposure needs.
• As a combined filter, users trade some flexibility versus carrying separate, dedicated filters for maximum control.

Our Verdict

For photographers and videographers who want a compact way to add a dreamy diffusion, moderate exposure control and reflection reduction, this 72mm 3-in-1 filter delivers good value and reliable performance. It is especially useful for portraits and landscape work where convenience and creative flexibility matter, though those needing extreme ND levels or complete separation of effects will prefer dedicated filters.

Frequently Asked Questions

Will this fit my lens?
It fits lenses with a 72mm thread; verify the diameter number printed on your lens before ordering.

Does the variable ND produce X cross artifacts?
The frame uses self-locking technology and is designed to rotate smoothly to avoid producing black cross artifacts across the ND range.

Can I use the CPL and ND together?
Yes, the design combines CPL and variable ND functionality so you can reduce reflections and control exposure simultaneously.
