K&F Concept Filtro ND variável 49mm Nano-C ND2-ND2000 (1-11 stops)

The K&F Concept Variable ND Filter 49mm Nano-C is a high-quality variable neutral density filter designed for photographers and videographers who need precise exposure control. With a density range from ND2 to ND2000 (1-11 stops), this filter allows you to achieve long exposures, shallow depth of field in bright conditions, and smooth cinematic motion blur. The advanced Nano-C multi-layer coating reduces reflections, flare, and ghosting while providing water, oil, and scratch resistance. Crafted from high-definition optical glass and an ultra-slim aviation aluminum alloy frame, it ensures minimal vignetting and neutral color balance.

Advantages

Variable ND filter offers stepless adjustment from 1 to 11 stops, eliminating the need to carry multiple fixed ND filters. The Nano-C coating ensures excellent image clarity and durability. Ultra-slim frame minimizes vignetting on wide-angle lenses. Smooth rotation mechanism allows quick and precise adjustments.
