NiSi NC UV Filter II with 49mm Front Thread for Fujifilm X100/X100S/X100F/X100T/X100V/X100VI (Black)

The NiSi NC UV Filter II with 49mm Front Thread is a protective UV filter built specifically for the Fujifilm X100 series, from the original X100 through to the X100VI. It threads directly onto the camera in place of the factory trim ring, and its new 49mm front thread lets you mount standard screw-in filters on top, turning a simple protector into the foundation of a compact, genuinely useful filter system.

Designed Specifically for the Fujifilm X100 Series

Every X100 body shares the same fixed 23mm f/2 lens, and this filter is machined to match it exactly. Remove the decorative ring, thread the filter into its place, and the camera keeps the clean profile that makes the X100 such a pleasure to carry. Nothing protrudes, and nothing needs removing before it goes back in a bag.

A 49mm Front Thread That Opens Up the System

The headline change in this version is the 49mm thread cut into the front of the frame. Any standard 49mm filter now screws straight on, so a circular polariser, a neutral density filter or a black mist can join the stack without adapters, step rings or extra bulk hanging off the front of a compact camera.

Macro-Friendly Design

Designed with precision industrial measurement, this macro-friendly construction provides dedicated space for the lens barrel to extend in close-focus and macro shooting. The result is smooth, unrestricted lens travel with zero mechanical interference, so you retain 100% of your lens’s native close-focusing performance. Capture extreme close-up detail with total confidence. No binding, no limitations, and no compromise.

Double-Sided Nano Coating with 99.3% Light Transmission

Both faces of the optical glass carry a multi-layer low-reflection nano coating that passes 99.3% of incoming light. Reflections that would otherwise bounce between the filter and the lens are suppressed, which keeps flare and ghosting under control when you shoot into street lights, shop windows or a low sun. Colour rendition stays neutral, so files still grade the way you expect.

Everyday Protection for a Lens You Cannot Replace

The X100’s lens is fixed, so damage to the front element is not something you can solve by swapping in another piece of glass. This filter takes the scratches, dust, sand and spray that any camera collects in daily use, and replacing it costs a small fraction of a lens repair or a trade-in.

Oil and Water Resistant Coating

The outer surface adds a hydrophobic and oleophobic layer, so rain beads and rolls away instead of drying into spots, and fingerprints, sunscreen and sea spray lift off with a single pass of a microfibre cloth. It is a small detail, and it matters most on exactly the days you are out shooting.

Compatible with the Original Lens Cap

The original Fujifilm X100 Series lens cap still fits directly onto the filter, so there is no need to carry a substitute or leave the front of the camera exposed between shots. The filter fits into the way you already work rather than asking you to change anything about it.

One-Piece Design with No Adapter Required

Many protective solutions for the X100 need an adapter ring first, adding length, cost and one more component to lose. This filter is a single machined unit that threads directly onto the camera, so fitting it takes seconds and the finished result sits almost flush with the lens barrel. Fewer parts also means fewer surfaces for dust to settle between.

Finished in Black to Match Your Camera

The slim aluminium frame is anodised in black to sit alongside the black X100 bodies, and the same filter is offered in silver for the silver version of the camera. The low-profile edge keeps the camera’s silhouette intact and the engraving stays discreet rather than advertising itself.

Whether you are working the street with an X100VI, travelling light with an X100V, or keeping an original X100 in service, the NiSi NC UV Filter II with 49mm Front Thread delivers permanent protection, genuinely clean optics and, for the first time in this range, a front thread that lets a fixed-lens compact grow into a full filter system.
