I had heard there was some issues about RAW conversion on the new Fujifilm cameras but couldn't figure out why. As it turns out, the new X-Trans sensor's RAW files aren't properly treated by the major image softwares, such as Adobe. Below is the same RAW file, converted to TIFF via Silkypix (latest version in trial version) and Adobe Photoshop CS6.
When zoomed 100% it is obvious that the files converted with Silkypix retain more detail.
I certainly hope Adobe will fix that in future updates!
