K&F Concept K&F 77MM, True Color Variable ND2ND400, ultra-thin adjustable filter KF01.2800

The K&F 77MM True Color Variable ND2ND400 filter is an ultra-thin, adjustable filter that provides optimal light reduction while maintaining true color accuracy. With advanced titanium coating, Japanese optical glass, and enhanced coatings, it delivers superior performance for video and photo shoots.

The K&F 77MM True Color Variable ND2ND400 filter is designed to offer photographers and videographers precise control over exposure while preserving color integrity. Using innovative titanium coating technology, the filter effectively eliminates yellowing during video shoots, ensuring true color reproduction. Its adjustable frame features infinite rotation between the 1st and 9th gears, making it easy to fine-tune light reduction for varying shooting conditions.

Constructed with top-grade Japanese optical glass and enhanced with 18 layers of coatings on both sides, this filter significantly reduces reflected light, preventing unwanted flare and maintaining image clarity. The CNC trapezoidal pattern design on the frame enhances grip, providing smooth rotation for easy installation and removal. The filters oxidized and sandblasted surface minimizes stray light, further reducing reflections and enhancing image quality in challenging lighting environments.
