Are the Fujifilm X-M5 and X-S20 X-Trans IV or V? Yes.

I’ve received a lot of questions lately about the Fujifilm X-M5 and X-S20. Specifically, people want to know what generation these two cameras fall under, and which Film Simulation Recipes they should use on their model. I’m not sure why this question has been asked so much lately, but there has definitely been a noticeable spike. Let’s get right into the answer, which is simple and complicated.
Both the X-M5 and X-S20 feature the same 26-megapixel X-Trans IV sensor found in the previous-generation models, such as the X-Pro3, X100V, X-T4, and X-T30 II. So it might seem obvious: they must be fourth-generation cameras, right? Not quite. Despite the sensor, both the X-M5 and X-S20 have the new X-Processor 5, the same as the X-T5, X100VI, X-H2, and X-T50, among others. In other words, these two cameras have a foot in both the X-Trans IV and X-Trans V worlds.
While sensor generation typically defines the era of Fujifilm cameras, it’s not just about the sensor itself—it’s also about the image processor, the firmware, and the JPEG engine. The X-Processor 5 brings with it some new Film Simulations, and a slightly divergent rendering (namely, the color blue on Classic Chrome, Classic Negative, Eterna, and Eterna Bleach Bypass). Even though the sensor on the X-M5 and X-S20 are from the prior generation, the JPEG options and rendering are more in line with the latest generation.

The most appropriate Film Simulation Recipes for the X-M5 and X-S20 are X-Trans V and not X-Trans IV. Recipes designed for X-Trans IV that use Classic Chrome, Classic Negative, Eterna, and Eterna Bleach Bypass might not look quite right, and will need a Color Chrome FX Blue adjustment. If the X-Trans IV Recipe (that uses one of those four Film Sims) calls for Color Chrome FX Blue set to Strong, use Weak instead; if it calls for Weak, use Off instead. With that simple adjustment, those X-Trans IV Recipes are fully compatible with the X-M5 and X-S20, as are all X-Trans IV (except those intended for the X-T3/X-T30) that aren’t based on those four Film Simulations.
While it’s a bit convoluted, the answers aren’t terribly complicated. Even though the X-M5 and X-S20 are a bit both X-Trans IV & V, they are indeed fifth-generation models. The Recipes that are most appropriate for these two cameras are the ones intended for X-Trans V cameras, like the X-H2s, X-T5, X100VI, etc., etc., but some X-Trans IV Recipes—those that don’t use Classic Chrome, Classic Negative, Eterna, and Eterna Bleach Bypass—are also fully compatible, and some are made compatible simply by reducing Color Chrome FX Blue down by one. Clear as mud? I hope this makes sense for those wondering which Recipes to use on their camera.
