As a casual glance, the sensors in the Fujifilm X100F and Ricoh GR III look like they could be the same. And in fact, at a hardware level that might actually be the case. Both provide 24MP worth of resolution and on-sensor phase-detection autofocus pixels, and image quality is broadly comparable. Image quality is also in line with many of the best 24MP APS-C cameras on the market when it comes to Raw detail and dynamic range.

The difference is in the filter arrays. Ricoh uses a conventional bayer-type filter array, whereas Fujifilm uses its own proprietary X-Trans design. If you're a JPEG shooter, there's a definite - albeit subtle - advantage to X-Trans when it comes to critical detail retention, across most of the X100F's ISO sensitivity range. And the X100F is well-suited to JPEG shooting, thanks to its suite of excellent Film Simulation modes, which replicate the look of classic Fuji film emulsions. We're less enthusiastic about the JPEG output from the GR III, particularly in terms of color.

On the other hand, the more conventional design of the GR III's sensor means that its Raw files play rather better with third-party Raw converters than those from the Fujifilm. While the difference isn't massive, and Capture One deserves a mention as one of the software suites that actually does a great job. It might make a difference if you're a Raw shooter with (for example) an established Adobe Raw workflow.

Verdict: Ricoh GR III's more conventional Raw files are more flexible.
