The problem is with how Adobe is processing the RAW image, if you use the converter that comes with the camera, it works just fine. Also implementations of DCRaw do not have the color smearing that adobe has, there has been no acknowledgement from Adobe as to whether or not they are doing anything about it. Capture One is working with Fuji to implement support. The problem with Chambers example is he has applied a lot sharpening to the image which really makes it become exaggerated. You can make it a lot less obvious by using clarity rather sharpening, but the color smearing is a problem that Adobe needs to rectify. They RC makes no changes.
I wish Eric Chan would at least comment as to whether or not they are working on the issue.
