K&F Concept Nano-C HMC Fader ND2-400 Variabel ND-filter 55mm

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 a density range of ND2 to ND400 (1 to 9 stops), this filter allows you to achieve slower shutter speeds and wider apertures even in bright conditions, perfect for long exposure photography and shallow depth of field effects.

Advantages

This variable ND filter offers stepless adjustment from ND2 to ND400, eliminating the need to carry multiple fixed ND filters. The 28-layer Nano-C multi-coating ensures excellent color neutrality, low color shift, and high definition. The ultra-slim rotating frame is made from aviation aluminum alloy, providing durability while minimizing vignetting. The anti-X cross design prevents the cross-shaped artifact that can occur at maximum density on some variable ND filters.

Suitable for

• Landscape photographers wanting silky water or cloud motion
• Portrait photographers needing wide apertures in bright light
• Videographers requiring precise exposure control
• Any photographer using lenses with a 55mm filter thread
