K&F Concept 77mm Nano-X Variable ND Filter ND32-ND512

Variable Neutral Density Filter Function

This variable ND filter reduces the amount of light entering the lens without affecting the overall color balance, enabling long exposure and motion blur techniques in varying lighting conditions.

Advanced Optical Design

• No X-Cross Effect: Utilizes K&F's peak technology to eliminate the "X" cross pattern commonly seen in variable ND filters.
• Frame Self-Locking Technology: The filter rotation stops precisely at minimum (ND32) and maximum (ND512) density settings for easy control.
• Top Optical Glass: Crafted from high-quality optical glass to maintain image sharpness, reduce glare, and ensure high-definition image quality.

Durable Multi-Layer Coatings

• 28 layers of nanometer coatings on both sides provide hydrophobic, waterproof, oil-resistant, and scratch-resistant properties.
• These coatings reduce surface reflectivity, enhancing image clarity and contrast.

Robust and Slim Frame

• Constructed from aircraft-grade aluminum with oxidation sandblasting for durability and to prevent stray light intrusion.
• Slim profile with a thickness of only 7.6 mm effectively prevents vignetting in wide-angle shots.
