Learn what the FUJIFILM AR-X100 Adapter Ring does, why you might need it, and how to use it to attach filters to your X100-series camera.
Quick Answer
The FUJIFILM AR-X100 Adapter Ring lets you attach standard 49mm threaded filters—like ND, CPL, or UV filters—to your X100, X100S, X100T, or X100F camera.
Why Use an Adapter Ring Instead of a Direct Filter?
The X100 series has a unique lens design with a non-standard front thread. Without the AR-X100, you cannot screw on most common filters. The adapter ring replaces the camera's original front ring, giving you a standard 49mm thread for creative or protective filters.
One trade-off: you must remove the stock front ring each time you install the adapter. It's a simple unscrew/screw process, but you'll want to keep the original ring safe if you ever want to revert to the stock look.
Frequently Asked Questions
- Which cameras work with the AR-X100?
- It fits the FUJIFILM X100, X100S, X100T, and X100F. It is not compatible with the X100V or later models, which have a different lens design. Check your camera model before purchasing—only the earlier X100 variants are supported.
- How do I install the adapter ring?
- Unscrew the original front ring on your X100-series lens by turning it counterclockwise. Then screw the AR-X100 ring clockwise until snug. Do not overtighten. Now you can attach any 49mm filter directly.
- Can I keep the adapter ring on all the time?
- Yes, you can leave it installed. It adds about 5mm of depth to the lens barrel. If you prefer the original look or need to use the lens cap that came with the camera, you may want to swap back. Store the original front ring in a safe place so you don't lose it.
Product Facts
- FUJIFILM AR-X100 Adapter Ring (Silver): The AR-X100 adapter ring replaces the original lens front ring on X100-series cameras, enabling use of any 49mm threaded filter. This means you can add a polarizer to reduce glare or an ND filter for long exposures, even though the lens itself doesn't have a standard filter thread.
