K&F Concept Filtro ND Variabile ND3-ND1000 62mm

The K&F Concept Variable Neutral Density Filter (ND3-ND1000) is a professional-grade filter designed for photographers and videographers who need precise control over exposure. With a 62mm thread, it fits a wide range of lenses and offers a variable light reduction of 1.5 to 10 f-stops, allowing for creative long exposures and cinematic effects.

Advantages

This filter provides seamless adjustment from ND3 to ND1000, eliminating the need to carry multiple fixed ND filters. The high-quality Japanese AGC optical glass and 28 multi-layer coatings ensure minimal color shift and excellent image clarity. The ultra-slim 7.4mm frame prevents vignetting even on wide-angle lenses, while the aviation aluminum alloy construction ensures durability. The smooth rotation mechanism with hard stops allows for precise and repeatable settings.
