KF 4-in-1 Nano-K UV CPL ND4 Filter Set 40.5 mm

Enhance your photography with the KF 4-in-1 Nano-K UV CPL ND4 Filter Set, designed for lenses with a 40.5 mm filter thread. This versatile kit includes three essential filters: UV, CPL, and ND4, each crafted from high-definition optical glass with Nano-X multi-coating for superior light transmission and protection. The ultra-slim aviation aluminum alloy frame ensures no vignetting, while the included protective pouch keeps your filters safe on the go.
