Clear the flash would be good, because he is strong. But the flash lights in focal range 24mm minimum 35mm (equiv. KB) throughout the lower part of incorrect. A comparison with the built-in flash shows the difference very clearly. This is possible both with my X-S1, as well as the case my X-10! The result always looks as if lightning had tilted slightly upward. I have replaced the flash, I have even had him for repair at Fuji themselves: Everything has brought nothing! Sorry, but I have never experienced in my long career. And I already had several brands. Why then at least 2 points: The interaction of the camera with the flash I like very much (when you first plugged the flash switched on the camera and then the camera to make).
