NiSi 67mm Ti Pro Nano UV Cut-395 Filter (Titanium Frame)

The NiSi 67mm Ti Pro Nano UV Cut-395 is a UV protection filter built with a titanium alloy frame instead of the heavier brass or aluminum most circular filters use, aimed at photographers shooting in cold weather where a lighter, more corrosion-resistant frame matters. Titanium's density is about half that of steel at the same weight, with roughly twice the hardness of aluminum and strong resistance to acid and base exposure, properties that also make it a material used in aerospace and missile construction. Its nano coating cuts UV light below 395nm while keeping high transmittance and ultra-low reflection, with a waterproof, anti-scratch surface that stays easy to clean.

• Titanium alloy frame: Roughly half the density of steel at the same weight, about twice the hardness of aluminum, and resistant to strong acid and base exposure — a material also used in aerospace and missile applications.
• Cold-weather performance: Titanium performs well in very low temperatures, unlike heavier brass or aluminum filter frames.
• UV-cutting nano coating: Cuts UV light below 395nm while maintaining high transmittance and ultra-low reflection on the glass surface.
• Waterproof, anti-scratch surface: A super-strong waterproof coating with anti-scratch resistance makes dust, fingerprints, and water stains easy to remove.
• High-definition optical glass: H-K9L standard optical glass is precision annealed to eliminate stress, passing strict HD testing with black matte paint around the glass edge to prevent stray light.
• Matte black interior finish: The inside of the frame is electroplated matte black to prevent internal reflection, while the outer ring is diamond-cut to show titanium's natural finish.
