K&F Concept filtro ND variabile ND8-ND2000 82mm

The K&F Concept Variable ND Filter ND8-ND2000 is a high-quality variable neutral density filter designed for photographers and videographers who need precise control over exposure. With a filter diameter of 82mm, this filter offers a density range from ND8 (3 stops) to ND2000 (11 stops), allowing for creative long exposure effects and wider apertures in bright conditions. Crafted with Japanese AGC optical glass and a 28-layer multi-coating, it ensures excellent light transmission, minimal color shift, and protection against water, oil, scratches, and reflections. The ultra-slim rotating frame is made from aviation aluminum alloy, minimizing vignetting even at wide angles, and the filter includes a front thread for attaching a lens cap or hood. No 'X' cross pattern appears at maximum density, ensuring consistent image quality.

Advantages

This variable ND filter provides seamless adjustment from 3 to 11 stops, eliminating the need to carry multiple fixed ND filters. The advanced multi-coating reduces flare and ghosting, while the slim design prevents vignetting on wide-angle lenses. The durable aluminum frame ensures long-lasting performance, and the neutral color balance preserves natural tones in your images.
