While a total newbie to this forum, I feel pressured to add a comment.
I recently bought an X-E2 (having got tired of lugging my heavy Pentax DSLR around while out trekking, etc). Though I love my Pentax, I am blown away by the quality of the X-E2 files (all Raw).
I spent a significant amount of time looking for a suitable converter. While I really love my LR 4.x, I have a problem at the moment with Adobe's CC plans, so have looked for alternatives (I am a PC, Win 7 user). Photo Ninja has some nice features, but I could find no way to do copy/paste of edits, so this was out. For financial reasons, I selected Capture One Express 7 (really great range of first-rate options, very well presented & easy to use) as I did not need the extras for the Pro version.
What followed was a nightmare - I was totally unable to activate my purchase, despite multiple attempts and numerous emails to Support. They ended up suggesting that I disable my firewall & antivirus software before trying the activation process again! Whoa, hello, why must I do such a stupid thing, something that I have never ever had to do before? Needless to say, I have now requested a full refund, & would to raise a minor alarm about this problem for other potential purchasers.
As a result, I have gone back to the SilkyPix which came with the camera. While not particularly friendly or easy to use, I have got wonderful results by using this to simply produce my tif file, then have continued the editing with an older version of Photoshop or LR - miles better than the C1 files. My thinking is that Fuji have helped & worked with these guys (who I have previously avoided, having LR) because they have been able to generate the best demosaicing algorithm for their X-trans files. Once I have a great quality tif, I can do whatever I want afterwards. I have been astounded at the sharpness of my edited file (with a little help from Topaz Detail) - examples available if anyone wants to see them.
While this process is more time-consuming than LR alone, the quality of the result more than justifies it - I am gob-smacked!
