K&F Concept Nano-C HMC Fader ND2-400 Variable ND Filter 52 mm

The K&F Concept Nano-C HMC Fader ND2-400 is a high-quality variable neutral density filter designed for photographers and videographers who need precise exposure control. With an adjustable ND range from ND2 to ND400 (1 to 9 stops), this filter allows you to achieve long exposures and shallow depth of field even in bright conditions. The 52 mm diameter fits a wide range of lenses, and the ultra-slim aviation aluminum alloy frame minimizes vignetting.

Advantages

This variable ND filter offers seamless adjustment of light reduction, eliminating the need to carry multiple fixed ND filters. The 28-layer Nano-C multi-coating reduces reflections, flare, and ghosting while providing water, oil, and scratch resistance. Japanese AGC optical glass ensures high image clarity and color neutrality, with an anti-green cast coating for accurate colors.

Suitable for

• Landscape photography with silky water or cloud motion
• Videography requiring consistent shutter speed and depth of field
• Portrait photography with wide apertures in bright sunlight
• Architectural and travel photography where variable ND is convenient
