K&F Concept 72mm Nano-X Variable ND Filter ND32-ND512 KF01.1473

K&F Concept 72mm 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

• Top Optical Glass: Crafted from high-quality optical glass to maintain image sharpness and reduce glare, ensuring high-definition image quality.
• 28 Multi-Layer Nano Coatings: Both sides of the glass feature nanometer-scale coatings that are hydrophobic, waterproof, oil-resistant, and scratch-resistant, minimizing surface reflectivity.

Innovative Mechanical Features

• 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.
• Aircraft-Grade Aluminium Frame: The frame is made from durable, oxidized sandblasted aluminium with a slim 7.6 mm thickness to prevent vignetting and block stray light.
