72mm Magnetic Variable ND Filter ND2-ND32 - Fast Swap, No X Cross

In this review the K&F Concept 72mm Magnetic Variable ND Filter ND2-ND32 is examined for photographers who need quick, reliable light control without introducing color shifts. The single biggest reason to consider it is the magnetic 1 second swap system that speeds filter changes dramatically compared with traditional threaded filters, making it a practical choice for run-and-gun landscape and video work. The kit reviewed includes the variable ND element and a 72mm magnetic basic ring, and it aims to preserve image quality while offering 1-5 stops of light reduction.

Key Features

• Magnetic 1 Second Swap: The magnetic adapter ring allows the filter to attach almost instantly, saving time when changing filters in the field.
• Frame Self-Lock: The anti-X design prevents the dark X pattern on wide-angle and telephoto lenses, improving usable range for the variable ND.
• High Definition Image: Japanese AGC optical glass is used to keep high resolution and avoid an obvious color cast in most shooting conditions.
• Adjustable Stops: The ND2-ND32 range provides approximately 1-5 stops of attenuation so photographers can control exposure and motion blur.
• Durable Coatings: Both sides have nanometer multi-layer coatings (28 layers) that are waterproof, scratch-resistant and reduce glare while protecting the lens.

Who It's For

This filter kit is suited to landscape, portrait and run-and-gun videographers using lenses with a 72mm front thread who want faster attachment and lightweight ND control without complex systems. The fast magnetic mounting is particularly useful when conditions change quickly and a threaded filter swap would slow a shoot.

Photographers who need extreme ND density beyond 5 stops, or who prefer screw-on stacking workflows, should look elsewhere; professionals needing guaranteed magnet performance in rough conditions may want a heavier-duty magnetic solution based on use-case testing.

Pros & Cons

Pros

• Quick magnetic attachment reduces time spent changing filters and simplifies workflow.
• Frame self-lock technology avoids the dark X artifact that can affect other variable NDs.
• Optical AGC glass and multi-layer coatings deliver solid image clarity without notable color cast.

Cons

• Magnet strength receives mixed feedback, so expect variability in hold under heavy handling.
• The variable range is limited to 1-5 stops, which may not suit users needing stronger long-exposure ND effect.

Our Verdict

The 72mm magnetic variable ND offers strong value for photographers who prioritize speed and convenience; the magnetic 1 second swap and anti-X frame make it a practical upgrade over basic screw-on variable NDs. It preserves image quality with quality glass and comprehensive coatings, but buyers should be mindful of the modest 1-5 stop range and occasional mixed reports on magnet strength.

Frequently Asked Questions

Does this kit include the adapter ring?
Yes, the package includes one ND2-ND32 variable filter and one 72mm magnetic basic ring; verify lens diameter before ordering.

Will the filter cause a color cast?
The glass is Japanese AGC and the design aims for no color cast; most users report neutral color balance in typical shooting situations.

Is the X pattern eliminated?
Frame self-lock technology is used to reduce the dark X artifact common to some variable NDs, improving performance on wide-angle and telephoto lenses.
