Review VerdictThe Fujinon XF 23mm f/2.8 R WR may be tiny, but it certainly delivers. It's sharp straight from f/2.8, and lateral CAs as well as image distortions are comparatively low. The vignetting is high in untouched files, but auto-correction does a good job with reducing the issue. The sunstar rendering is Ok, but nothing to brag about. With these specs, the bokeh potential is rather underdeveloped. The 2nd biggest (or biggest?) asset of the XF 23mm f/2.8 R WR is, of course, its cute form factor and extremely low weight - while maintaining a very good build quality, including weather sealing. The AF stepping motor is conceptually dated, but it does the job. It's not a cheap lens, but that's the price to pay for a quality pancake lens. If you can live with the rather slow speed (for a prime lens), the XF 23mm f/2.8 R WR is certainly an interesting candidate for your camera bag. Combined with one of the smaller Fujifilm cameras, it's also a tempting option for those who want to minimize their travel gear.

Where can this lens be adapted?

The Fujifilm X mount has a flange distance of 17.7 mm. A plain adapter fits a camera whose flange distance is at least 1.46 mm shorter. How lens adapters work

Native lenses set the aperture, and often the focus, electronically. On a plain adapter they do not work. Use an electronic adapter made for this pair; for many pairs nobody makes one. Fully manual lenses are the exception.
