Shooting a festival this weekend ran into an issue with the XP2. Many files that had (very) high lighting range showed a mirror image if the bright subject, flipped around an imaginary x-y center axis. This happens on both bodies, and with all 3 lenses used (23/1.4, 35/1.4, 56/1.2).
The first image, at twilight, had a moderate ev range, yet the giant screen tv image shows as a reflection towards upper-right.
