Learn what the FUJIFILM AR-X100 adapter ring does, how to install it on your X100-series camera, and why it lets you use 49mm filters for creative control.
Quick answer
The FUJIFILM AR-X100 adapter ring lets you attach any 49mm threaded filter to your X100, X100S, X100T, or X100F camera by replacing the original lens front ring.
Why you might need this adapter ring
The X100-series lens has a unique front thread that doesn't accept standard filters directly. The AR-X100 solves that by swapping the factory ring for one with a standard 49mm female thread. This opens up the use of UV, polarizer, and neutral density filters without a bulky step-up ring or third-party hood.
How to install the AR-X100 adapter ring
- Remove the original front ring: Hold the camera steady and unscrew the existing front ring from the lens barrel. Turn counterclockwise until it comes off. Be careful not to scratch the lens element; work over a clean, soft surface.
- Screw on the AR-X100 adapter ring: Align the threads of the adapter ring with the lens barrel and turn clockwise until finger-tight. Do not overtighten. If the ring feels cross-threaded, stop and realign. Forcing it can damage the threads.
- Attach your 49mm filter: Screw any 49mm filter (UV, polarizer, ND, etc.) onto the adapter ring. The filter should seat flush without wobble. Check that the filter does not block the viewfinder or flash on your X100 model.
