K&F Concept 77mm Variable ND2-400 D-Series ND Lens Filter 1-9 Stops Adjustable Waterproof Japanese Optical Glass

The K&F Concept 77mm Variable ND2-400 D-Series ND Lens Filter is crafted from premium Japanese optical glass, designed to provide exceptional light control for your photography. Its ultra-thin 7.4mm profile and durable construction make it an essential tool for photographers.

Features:
* Precision Optics: Made from top-tier Japanese optical glass with double-sided 24-layer enhanced coating to effectively reduce surface reflections and prevent glare during prolonged exposures.
* Enhanced Water Resistance: Multi-layer waterproof coating ensures water remains in droplet form, making the filter easy to clean and maintain.
* Versatile Light Control: Offers 1 to 9 stops of adjustable light reduction with 360-degree rotation for precise dimming settings, suitable for various shooting conditions. (Note: High settings may cause a temporary "black cross" effect, which is natural for adjustable ND filters with certain lenses.)
* Slim and Secure Design: At just 7.4mm thick, the CNC-patterned design provides enhanced friction for easy attachment and detachment.
* Glare-Free Surface: Treated with an oxidized sandblasting process to prevent unwanted stray light and minimize reflections on the metal surface.
* Compatibility: Designed for all 77mm lenses. An 82mm lens cap is required for this variable ND filter.
