Aluminium + Optical Glass Filter Kit

Compact, 3g lens filter system built around optical-grade glass and aerospace-grade aluminium alloy — designed specifically for Insta360 GO Ultra’s form factor and optical path. Multi-layer anti-reflective coating guarantees minimal flare, high transmission and faithful colour reproduction. Provides physical safeguarding against daily wear — including sand, fingerprints, rain splashes and incidental contact — without introducing distortion, focus shift or resolution loss. The UV filter improves clarity in high-UV environments (beaches, alpine zones, glaciers) by filtering out invisible UV wavelengths that desaturate blues and induce haze. CPL filter rotates independently to selectively cancel reflected light — enhancing contrast between sky and clouds, revealing underwater detail, and eliminating glare from wet pavement or car windows. ND filters enable creative exposure settings: ND8 allows 1/60s shutter in noon sun; ND64 enables 1/4s motion blur — unlocking cinematic techniques impossible with auto-exposure alone. Black Mist 14 gently scatters intense highlights for smoother tonal transitions, especially valuable in backlit or high-contrast street scenes. Modular set options include 3-in-1 (CPL+ND16+Black Mist 14), 3-in-1 Mixed (CPL+ND8+ND16), 4-in-1 Mixed (MCUV+CPL+ND32+ND64), 4-in-1 ND stack (ND8/16/32/64), 4-in-1 NDPL (polarised ND), and full-coverage 6-in-1 (CPL+ND8/16/32/64+Black Mist 14) — all tested for GO Ultra’s thermal stability and magnetic attachment integrity.
