## Long description

Neutral Density Filter K&F Concept Nano-C HMC Fader ND2–400 52mm adjustable density offers variable light reduction from ND2 to ND400 in a slim 52 mm threaded design. It controls exposure in bright conditions to enable longer shutter speeds and wider apertures for landscape, long-exposure and video work while maintaining image quality through optical glass and multi-layer coatings.
Advantages
The filter provides smooth, continuous ND adjustment across a wide range (ND2–ND400), allowing precise control of exposure. Constructed from optical glass with double-sided multi-layer blue Nano-C/HMC coatings, it reduces reflections, improves contrast and is water-resistant. A slim 7.3 mm frame and a lightweight CNC-machined ring keep the filter compact and reduce the chance of vignetting or imbalance when used on a tripod.
Suitable for
Landscape photography
Long exposure images of waterfalls, rivers and seascapes
Creating motion blur in daylight
Video work requiring exposure control

How to use
Screw the 52 mm filter onto the front thread of a lens with matching diameter. Rotate the adjustable ring to change the density from ND2 up to ND400 to achieve the desired exposure reduction. Use higher density settings for longer shutter speeds or shallower depth of field in bright light; use lower settings for subtle reductions in exposure. When composing long exposures, mount the camera on a tripod to avoid motion blur from camera shake.
Usage recommendations
Check compatibility with your lens thread size before purchase. Start at lower density and increase gradually while monitoring exposure and live view. When using extreme ND values, focus and compose before applying maximum density or use manual focus and then recompose. Clean coated surfaces with a microfibre cloth and store the filter in a protective case to preserve coating performance.
