Clear 82mm UV filter with thin aluminium ring and knurled edge

Haida

Haida Bluestone Shock-Proof UV Filter 82mm #HD4783-82

SKU CH-96PR-2DHBD

Shock-proof UV filter with 99.4% light transmission, 24-layer coating, waterproof and oil-proof surfaces, and a 3.1mm ultra-thin frame to prevent vignetting

  • Schott B270 glass delivers up to 99.4% light transmission for clearer images
  • 24-layer coating cuts reflections and boosts transmittance on both sides
  • Ultra-thin 3.1mm frame with knurling prevents vignetting and ensures easy grip
  • Aviation-grade aluminum ring provides secure fit and uniform surface gloss
  • Double-sided waterproof and oil-proof coating resists harsh environments

Shock-proof UV protection for 82mm lenses

The Haida Bluestone filter uses Schott B270 glass to shield front elements from impact, dust and moisture. An aviation-grade aluminium ring provides precise threading and a uniform surface finish. The 3.1mm ultra-thin profile with knurled edges prevents vignetting on wide-angle lenses. It is built for photographers who need reliable defence in demanding outdoor conditions.

99.4% transmission with 24-layer coating

Light passes through the glass at up to 99.4% thanks to twelve coating layers on each side. Reflections and flare are reduced across the spectrum for cleaner contrast. Double-sided waterproof and oil-proof treatments repel rain, spray and fingerprints. The slim frame adds negligible mass to the lens barrel during extended shooting sessions.

Upgrades basic clear or single-coated filters

Replaces simple protectors that lack shock resistance or multi-layer anti-reflection performance. The jump is worth it when shooting against bright skies, near water or in dusty environments where durability and clarity matter. Not suited for buyers who need neutral density or polarising effects, or who require a filter thread size other than 82mm.

Questions about this item

How do I install the Haida Bluestone 82mm UV filter without cross-threading the aviation aluminium ring?

Align the filter threads with the lens front threads, turn gently until you feel the first engagement, then rotate smoothly using the knurled 3.1mm frame until snug; the precision-engineered threads on the aluminium ring prevent binding when started straight.

What cleaning routine keeps the 24-layer double-sided waterproof and oil-proof coating effective?

Blow off dust with a blower brush, then wipe with a microfibre cloth lightly dampened with lens cleaning fluid; the hydrophobic and oleophobic layers on the Schott B270 glass repel water and oil, so gentle circular motions are enough without degrading the coating.

At what light-transmission threshold does the 99.4% Schott B270 glass start to limit exposure in sustained high-contrast shooting?

The glass transmits up to 99.4% of incoming light, so only a fraction of a percent is lost; in practice this appears as a negligible exposure shift that is easily compensated by the camera’s metering during extended high-contrast sessions.
