Finally Adobe released ACR v7.1 and Lightroom v4.1 that adds support for the X PRO 1.  Diglloyd posted a first test using the new Adobe RAW converter. Let me know if you find more tests with the new Adobe RAW converter! I am curious to see if Adobe managed to get out more from the X RAW files than other RAW programs!

UDPATE: Soundimagesplus posted a full Adobe converter test: “ACR is obviously a much more responsive and flexible programme, but it does seem that the unique nature of the sensor means that some of my normal techniques may not work so well. Interestingly, I have a preset saved that defaults to the parameters in the previous version of the Camera Raw plug-in, and I felt that I got slightly better results.“
