which would be the best raw processor for the XE-1?

Another possibility is Capture One Express. It is only $99 and should include the X-trans conversions soon, but hopefully will be upgraded to version 7 since version 6 is over two years old. I am waiting to see if that happens. I would do the basics of raw conversion then open in Photoshop to finish off which is what I always do, plus I could use my plugins, like Topaz and Nik Viveza. Topaz Denoise has the best noise reduction and i prefer to do selective adjustments on layers.

Anyway, it doesnt exist yet, neither does Accuraw which I want to test out once it is finished. Right not i am shooting jpeg and can see doing that for 90% or more of my fuji pictures
