Neutral Density Variable Magnetic Filter K&F Concept Nano-X MRC Fader ND2-32 72 mm

The Neutral Density Variable Magnetic Filter K&F Concept Nano-X MRC Fader ND2-32 72 mm is a variable ND filter designed to provide adjustable light reduction for photography and video. It offers a magnetic mounting system for quick attachment and removal, a multi-resistant coating (MRC) to minimize reflections and flare, and a continuous density range from ND2 to ND32 to control exposure and motion blur without changing filters.

Advantages

The magnetic design enables fast and secure assembly on lenses with compatible magnetic adapter rings, reducing setup time when switching filters. The Nano-X multi-resistant coating improves contrast by reducing internal reflections and resisting fingerprints, dust, and moisture for easier cleaning and longer-lasting optical performance. The variable ND range from ND2 to ND32 provides flexible control over shutter speed and aperture, allowing smooth transitions between brightness levels during stills and video work.

Suitable for

• Landscape photography requiring long exposures to smooth water and cloud movement
• Long-exposure urban and architectural photography
• Video production where adjustable light reduction is needed without interrupting recording
• Outdoor portraiture in bright conditions to enable wider apertures for shallow depth of field

Key specifications

• Filter type: Variable neutral density (ND) filter
• Density range: ND2 to ND32 (adjustable)
• Mount diameter: 72 mm
• Mounting: Magnetic attachment compatible with magnetic adapter systems
• Optical treatment: Multi-Resistant Coating (MRC) to reduce reflections and resist contaminants
• Intended use: Controls exposure and motion blur for photography and video

How to use

Mount the compatible magnetic adapter ring to the front of your lens if not already fitted. Attach the filter magnetically to the adapter and rotate the filter element to adjust the density between ND2 and ND32 until the desired exposure or motion-blur effect is achieved. Monitor exposure settings in-camera or with an external meter when making large adjustments. When shooting video, make smooth, deliberate rotations to avoid abrupt changes in scene brightness. After use, detach the filter magnetically and store it in its protective case to prevent scratches.

Usage recommendations

For best results, combine the filter with a sturdy tripod when making long exposures and use live histogram or highlight warnings to verify correct exposure. Avoid stacking additional filters that may introduce vignetting or exacerbate cross-polarization effects. Clean the filter with a soft microfiber cloth and lens-safe cleaning solution to maintain the multi-resistant coating.
