NiSi 42252 67mm Pro Nano HUC UV Lens Filter

The NiSi 67mm Pro Nano HUC UV Filter is purpose-built for photographers who keep a protection filter permanently mounted on their working lenses and refuse to accept any optical penalty for doing so. At 67mm, it fits a wide range of popular midrange zooms and fast primes — the kinds of lenses that live on cameras and see daily use in the field. The Japanese ultraviolet absorption optical glass delivers 99.2% transmittance with double-sided multi-coating, which translates to images that are indistinguishable from bare-lens shots. There's no softness creeping into corners, no warm or cool color shift, and no measurable light loss — it's the kind of filter that earns its place by being genuinely undetectable in your work.

What separates the NiSi Pro Nano HUC from the stack of generic UV filters in every camera shop is the build quality and coating performance you experience in the field. The brass frame is precision-milled to tight tolerances, producing threads that mate smoothly with your lens and resist the binding and cross-threading that can turn filter removal into a white-knuckle experience. The ultra-thin profile keeps vignetting out of the equation on the moderate wide-angle focal lengths typical of 67mm lenses. And the proprietary "U" type Nano coating proves itself on location — water beads and rolls away, dust doesn't adhere, fingerprints wipe clean in a single pass, and scratches are resisted rather than absorbed. For photographers who spend long days outdoors and need their glass protected without compromise, the NiSi 67mm delivers quiet, confident reliability shoot after shoot.
