Filtro ND variable K&F Concept ND3-ND1000 37mm - Filtro de densidad neutra ajustable

The K&F Concept Variable Neutral Density Filter (ND3-ND1000) is a high-quality adjustable filter designed for photographers seeking creative control over exposure. With a 37mm thread, it fits compact cameras and lenses, allowing smooth transitions from 1.5 to 10 stops of light reduction. Crafted from Japanese AGC optical glass and aviation aluminum alloy, it features a 28-layer nano coating for waterproof, oil-proof, scratch-resistant, and anti-reflection performance. The ultra-slim frame prevents vignetting, while the innovative design eliminates the 'X' cross pattern at maximum density. Ideal for long exposures, motion blur, and shallow depth of field in bright conditions.

Advantages

This variable ND filter offers unparalleled versatility, replacing multiple fixed ND filters. Its precise rotation mechanism enables quick adjustments without removing the filter, saving time in dynamic shooting environments. The multi-layer coating ensures minimal color shift and maintains true color balance, while the double-sided polishing delivers high-definition image quality. The robust aviation aluminum frame is lightweight yet durable, making it an essential tool for both amateur and professional photographers.

Suitable for

• Landscape photography requiring long exposures for silky water or cloud motion
