K&F Concept 77MM ND4-ND64 Variable ND & CPL Filter 2-in-1

K&F Concept 77MM ND4-ND64 Variable ND & CPL Filter

The K&F Concept 77MM ND4-ND64 Variable ND & CPL Filter combines a neutral density (ND) filter and a circular polarizing (CPL) filter into a single unit, providing 2 to 6 stops of light reduction. This versatile filter is designed to control exposure in bright lighting conditions, enabling long exposure photography and motion blur effects while enhancing color saturation and reducing reflections.

Key Features

• 2-in-1 Functionality: Offers variable ND filtering from 2 to 6 stops (ND4 to ND64) to manage light intensity, combined with a CPL filter that improves color vibrancy and eliminates unwanted reflections.
• No X Cross Effect: Features a self-locking frame design that prevents the X cross pattern commonly seen in variable ND filters when used with wide-angle lenses.
• Easy Adjustment: Constructed with an aluminum alloy frame and a convenient putter design, allowing precise and smooth control over light reduction levels.
• Anti-Reflection Treatment: Equipped with a 28-layer anti-reflective coating that is waterproof and scratch-resistant, minimizing stray light and reflections to ensure sharp image quality.
• Durable Build: CNC-machined non-slip aluminum frame provides secure handling, even when wearing gloves.
• Lens Compatibility: Designed to fit all lenses with a 77mm thread size; users should verify their lens thread diameter before purchase.
