Filtro ND variável K&F Concept Série Nano-X ND3-ND1000 55mm

The K&F Concept Nano-X Series Variable Neutral Density (VND) Filter is a professional-grade lens filter designed for photographers and videographers who need precise exposure control. With an adjustable ND range from ND3 to ND1000 (1.5 to 10 stops), this filter allows you to capture long exposures, smooth motion blur, and shallow depth of field even in bright conditions. The 55mm thread size fits a wide range of lenses, and the ultra-slim 7.4mm frame minimizes vignetting on wide-angle lenses.

Advantages

This VND filter offers seamless adjustment of light reduction without the need to carry multiple fixed ND filters. The multi-layer nano-coating (28 layers) provides waterproof, oil-proof, scratch-resistant, and anti-reflection properties, ensuring clear and sharp images. The Japanese AGC optical glass maintains high-definition optical resolution with minimal color shift, while the aviation-grade aluminum alloy frame is durable yet lightweight. The smooth rotation mechanism with hard stops allows precise setting and eliminates the X-cross effect at maximum density.

Suitable for

• Landscape photography requiring long exposures
• Videography needing consistent shutter speed and depth of field
• Portrait photography in bright light to use wide apertures
• Any photographer using lenses with 55mm front filter thread

Recommendations

For best results, use this filter with lenses that have a 55mm filter thread. Ensure the filter is securely attached and rotate smoothly to achieve desired ND effect. Avoid using at maximum density with ultra-wide lenses to prevent potential vignetting. Clean with a microfiber cloth to maintain coating integrity.
