K&F Concept 82mm Variable ND2-ND32 & CPL 2-in-1 ND + Circular Polarizer Lens Filter

Two-in-one functionality: Combines variable Neutral Density (ND2–ND32) and Circular Polarizing (CPL) filters in a single unit to both reduce incoming light and suppress reflections from non-metallic surfaces like water and glass. Advanced variable-ND design eliminates the typical "X" cross artifact on wide-angle shots using K&F Concept’s updated technology. Construction and optical performance: Built from AGC optical glass with a 28 multi-layer coating. The element permits only 0.2% light transmittance, is waterproof and scratch-resistant, and helps protect your lens. For this 77mm ND filter, the lens cap/hood should be 86mm. Frame and controls: The filter frame is aluminum alloy with a CNC non-slip edge for easier mounting and removal. Five index marks from Min to ND32 on the rim let you quickly set and confirm the ND position. Important note: Confirm your lens thread diameter (usually stamped on the lens barrel or under the lens cap) before purchase. The size is indicated by a "ø" (diameter) symbol; for example, Ø58 = 58mm thread size, Ø37 = 37mm thread size. Package contents: 1x ND2-ND32&CPL filter (NANO-X series) and 1x filter box.
