77mm UV protection for outdoor shooters

The Haida Bluestone Shock-Proof UV Filter uses Schott B270 glass to shield lenses from dust, rain, fingerprints and scratches while maintaining sharp, clear images. A 24-layer coating on both sides reduces reflection and pushes light transmittance to 99.4%. Its 3.1mm ultra-thin aviation aluminium frame prevents vignetting on wide-angle lenses. The knurled edge gives a secure grip for quick changes in the field.

Replaces basic clear or uncoated filters

Photographers moving up from simple protectors gain multi-layer anti-reflection performance and double-sided waterproof and oil-proof coatings that shed moisture and smudges. The upgrade is worth it when shooting in harsh weather or high-contrast light where flare and ghosting degrade detail. The hardened B270 substrate resists impact better than standard optical glass, extending the life of expensive front elements.

Fits any 77mm thread without adding bulk

The slim 3.1mm profile leaves clearance for lens caps and hoods, while precision-machined threads ensure a secure, light-tight seal. No extra adapter rings are needed, and the filter can stay mounted permanently as a sacrificial barrier. It frees the photographer from frequent front-element cleaning and protects resale value of the lens underneath.

Questions about this item

Will the 77mm thread and 3.1mm frame clear my lens hood?

The 77mm thread matches 77mm lenses and the 3.1mm ultra-thin frame avoids vignetting on wide angles

How do I seat the knurled ring without cross-threading the aluminum?

Align the threads, turn gently until resistance drops, then tighten with fingertips only — no tools needed

Can the 24-layer coating be cleaned safely after salt spray?

Yes, the double-sided waterproof and oil-proof coating resists salt; wipe with a microfibre cloth and lens fluid
