K&F Concept 49mm Variable ND Lens Filter (ND2-ND400)

Premium Quality Optical Glass

Crafted from high-grade AGC optical glass, this ND filter features an impressive 18 multi-layer coatings, significantly reducing reflections and glare. This ensures superior image quality, making it a standout choice for photography enthusiasts and professionals alike.

Versatile Light Control

With adjustable light reduction ranging from 1 to 9 stops, and a 360-degree rotation for precise dimming settings, this filter is perfect for various shooting scenarios. Note that higher stops may cause a cross-pattern effect, commonly known as an "X black cross." This is a natural and temporary phenomenon that occurs due to the interaction between the adjustable ND filter and certain lenses and focal lengths.

Glare-Free Surface

The filter is treated with an oxidized sandblasting process, effectively preventing unwanted stray light and minimizing unnecessary reflections on the metal surface. This ensures a clean and clear image every time.

Slim and Secure Design

At just 7.4mm thick, this CNC-patterned design offers enhanced friction while rotating, making it easy to attach or detach lenses and accessories anytime, anywhere.

Compatibility

This ND filter is compatible with all 49mm lenses. Please check your camera's lens thread size, usually indicated by a "ø" diameter symbol. Additionally, a 52mm lens cap is required for this 49mm variable ND filter.
