NiSi UHD UV Camera Lens Filter Fujifilm X100 Series

The NiSi UHD UV is a purpose-built lens protector engineered exclusively for the Fujifilm X100 series — not a generic 49mm filter adapted for use, but a dedicated solution that mounts directly to the X100's fixed lens barrel. Its primary function is mechanical protection: optical glass rated to resist scratches, dust, and moisture, backed by NiSi's Pro Nano Coating that adds waterproof and oleophobic surface properties. The UV filtering capability cuts light below 365nm, which reduces atmospheric UV haze in outdoor shooting and prevents the subtle color contamination that uncoated lenses can pick up in bright midday or high-altitude conditions. At 99.3% transmittance, it is designed to be optically invisible — something the X100's already-excellent Fujinon lens deserves.

For street, travel, and documentary photographers who carry an X100 series camera as a primary or companion body, the value of a dedicated front element protector is real: the X100's fixed lens cannot be swapped out if scratched, making front glass protection a practical investment rather than a theoretical one. The silver frame version is clearly targeted at silver-body X100 cameras, maintaining the camera's industrial design integrity rather than introducing a mismatched accessory. The installation note — removing Fujifilm's standard mounting ring first — is a one-time setup step, after which the filter fits cleanly and stays put. It suits any X100 shooter who takes the camera into challenging environments, from city streets in rain to dusty outdoor markets, and wants permanent front element protection with zero optical penalty.
