Fujifilm GFX100RF Wide Conversion Lens Option
Recently, I wrote an article about yet another WCL and TCL conversion lens set coming to the X100 system—this time from Viltrox. In that piece, I also expressed my hope that someone would finally create conversion lenses for the Fujifilm GFX100RF as well.
Well, while we don’t have any conversion lens specifically designed for the GFX100RF, it looks like the Ricoh GW-4 wide conversion lens actually works fine also on the Fujifilm GFX100RF.

I have found a video about it and also a blog post, you can find both of them below.
Summary of the video:
- The Ricoh GW-4 wide-angle converter delivers surprisingly high image quality on the GFX100RF.
- Sharpness remains strong, both in the center and corners, even with 100MP files.
- Contrast stays consistent with the native lens; no noticeable loss in micro-contrast.
- Minimal corner softness at typical landscape apertures (f/11–f/16).
- Distortion is very low for a wide-angle converter and easily corrected when visible.
- Flare control is good — lamps and bright light sources show no major artifacts.
- Vignetting is minor and natural-looking, often negligible in real use.
- Overall: delivers a clean, wide 21mm-equivalent image without the usual compromises of cheap add-on lenses.
