While not particularly relevant to this thread, interestingly I returned the first x-E1 I received. Lousy AF (unsharp images) and terrible shutter lag. However, I am totally in love with it's replacement. I am extremely glad that I didn't ask for a refund. Bearing in mind that everybody raves about the IQ of the Fuji 100's sensor, which the X-E2 has, I strongly suggest you got a duff one. Send it back for replacement - don't waste any more time and effort on testing.
