K&F Concept 49mm Variable ND2-ND400 (1-9 Stops) ND Lens Filter B-Series

This K&F Concept variable neutral density filter for camera lenses is crafted from premium AGC optical glass with 8 multi-layer coatings, effectively reducing reflections and glare for superior image quality. It offers versatile light control with 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, making it ideal for diverse photographic scenarios. The filter is treated with an oxidized sandblasting process to prevent unwanted stray light and minimize reflections on the metal surface. At a mere 7.4mm thickness, its CNC-patterned design ensures enhanced friction for easy attachment and detachment. This ND filter is compatible with all 49mm lenses. Please verify your camera's lens thread size before ordering. When using the ND filter to its maximum density, a cross-pattern effect (X black cross) may appear; this is a natural and temporary phenomenon due to the interaction with specific lenses and focal lengths.
