55mm Shock-Proof UV Filter for Lens Protection

The Haida Bluestone UV filter fits 55mm threads and shields front elements from dust, rain, fingerprints and scratches. Schott B270 glass transmits up to 99.4% of light for clear, sharp results. It suits photographers who want daily protection without sacrificing optical quality.

Aviation Aluminum Frame

The frame uses lightweight aviation-grade aluminum with regular threads and knurled edges for secure grip. At 3.1mm thick the ring avoids vignetting even on wide-angle lenses. Uniform surface finish and precise threading make mounting and removal smooth in the field.

24-Layer Dual-Sided Coating for Water

Twelve layers per side cut reflections and boost transmittance across the surface. The coating repels water and oil, so droplets and smudges wipe clean quickly. This durability helps maintain image clarity during extended outdoor shooting sessions.
