K&F Concept Nano-C HMC Fader ND2-400 variabilný ND filter 77 mm

The K&F Concept Nano-C HMC Fader ND2-400 is a high-quality variable neutral density filter designed for photographers seeking creative control over exposure. With an adjustable ND range from ND2 to ND400 (1 to 9 f-stops), this filter enables long exposure effects, motion blur, and shallow depth of field even in bright conditions. The 77 mm diameter fits a wide range of lenses.

Advantages

Variable ND filter eliminates the need to carry multiple fixed ND filters. The 28-layer nano multi-coating reduces reflections, flare, and ghosting while providing water, oil, scratch, and dust resistance. The ultra-slim 7.4 mm aviation aluminum alloy frame minimizes vignetting and is compatible with wide-angle lenses. Special optical design eliminates the 'X' cross vignetting common in variable ND filters.

Suitable for

• Landscape photography with silky water or cloud motion
