K&F Concept filtro ND variabile ND8-ND128 72mm

The K&F Concept Variable ND Filter ND8-ND128 is a high-quality neutral density filter designed for photographers and videographers who need precise control over exposure. With a variable range of 3 to 7 stops (ND8 to ND128), this filter allows you to achieve long exposures and smooth motion blur even in bright conditions. The 72mm diameter fits a wide range of lenses, making it a versatile addition to your camera kit.

Advantages

This variable ND filter offers exceptional color neutrality and sharpness, thanks to its Japanese AGC optical glass and 28-layer multi-coating. The coatings provide waterproof, scratch-resistant, anti-reflection, and anti-oil properties, ensuring durability and easy cleaning. The ultra-slim frame minimizes vignetting, and the double-sided polishing technology enhances image quality. Additionally, the filter is designed to prevent the 'X' cross pattern at maximum ND, giving you consistent results.
