72mm Black Diffusion Mist Variable ND2-400 Filter - Soft Highlights

In this review the K&F CONCEPT 72mm Black Diffusion Mist Variable ND2-400 is evaluated for photographers and videographers seeking a compact way to combine neutral density and diffusion in a single filter. The bottom line: it is best for creative shooters who want consistent light reduction from ND2 to ND400 while also softening highlights and reducing contrast for a dreamy look. The review finds the putter-adjustable frame and 28 multi-coated AGC optical glass make it a practical, durable tool for outdoor and studio use.

Key Features

• 2-in-1 design: Combines variable neutral density with a black diffusion mist effect so users can both reduce exposure and soften highlights without swapping filters.
• Putter adjustable frame: The unique putter-shaped frame gives tactile indexing and marked stops from ND2 to ND400 so exact light control is faster and repeatable.
• Wide ND range: ND2 to ND400 covers roughly 1 to 9 stops of light reduction, making it useful from slight attenuation to heavy long-exposure looks.
• AGC optical glass: Made with imported AGC glass and 28 multi-layer coatings for clear images and long-term resistance to water and scratches.
• Durable coatings: Hydrophobic and oil-proof coatings on both sides help keep the filter clean during adventurous outdoor shoots.

Who It's For

This filter suits landscape photographers, run-and-gun videographers, and portrait shooters who want to blend exposure control with a gentle diffusion effect in one compact accessory. The variable ND makes it ideal for scenes where lighting changes and the marked stops let users make consistent adjustments between takes.

It is less appropriate for users who need absolute clinical sharpness with zero flare in every situation or for those who prefer fixed-strength glass diffusion or ND filters for the purest optical consistency. Also verify your lens has a 72mm thread before ordering.

Pros & Cons

Pros

• Combines ND and diffusion, reducing the need to stack multiple filters in many creative scenarios.
• Clear stop markings and putter-style adjustment enable repeatable exposure changes for video work.
• High-quality AGC glass with 28 multi-coatings offers good image quality and surface protection.

Cons

• Some users may notice increased flare in certain highlight arrangements when using the diffusion effect.

Frequently Asked Questions

Will this fit my lens?
It fits lenses with a 72mm filter thread; check the diameter number next to the thread mark on your lens before buying.

Can I use the filter for long exposures?
Yes, the ND2 to ND400 range allows for long-exposure work when combined with appropriate shutter speeds and a tripod.

Does the diffusion affect sharpness?
The black diffusion mist softens highlights and lowers contrast by design, which can slightly soften perceived microcontrast though center resolution remains good thanks to AGC glass.
