K&F Concept Filtro ND variabile ND2-ND32 77mm

The K&F Concept ND2-ND32 Variable Neutral Density Filter is a versatile tool for photographers and videographers seeking creative control over exposure. With a variable density range of ND2 to ND32 (1-5 stops), this filter allows you to adjust light reduction seamlessly, enabling long exposures, shallow depth of field in bright conditions, and smooth cinematic motion blur. Crafted from Japanese AGC optical glass and aviation aluminum alloy, it ensures high-definition clarity and durability. The 28-layer nano-coating provides waterproof, scratch-resistant, oil-proof, and anti-reflection properties, while the ultra-slim double-threaded frame minimizes vignetting and allows for lens cap attachment.
