Fuji has a 15-year or so history of using unusual or different sensor types. By my count, the X-trans would be their third major type of "maverick" sensor type. You know, one summer, I think 2006 or 2007 it was, I took a whole batch of files from two different cameras, Canon 5D and Nikon D2x, and then ran them as batches through automated processing using MacBibble, SilkyPix, DPP, and Nikon Capture I want to say 4.0, as well as the Adobe Camera Raw module, of I think it was, Photoshop CS using the Automate Batch process.
It was really,really interesting to see how the different raw conversions created different moods, or feelings, to the same images. On most images, the average look was fine; but out of the 50 or so test files, there were always five or six that would be simply OUTSTANDING in the way one of the pieces of software would decode and interpret the data.
