I asked about the shutter in the X5S being electronic or mechanical. The new X4S is mechanical which should alleviate the rolling shutter issues, but the more expensive X5S will still have them being non-mechanincal.
From what I read on the electronic ones, if I am to believe the online techs, you can select a speed of say 1/4000 sec. but that is the time the actual pixel is switched on and off. The time it takes for the complete scan of the entire frame can take much longer, up to 1/10 second in some electronic shutters, and maybe only 1/60 in ones who can only cover 60 frames per second. So it is sort of misleading saying 1/4000 while the actual frame scan is longer, but that's what it is and why the rolling shutter and bent moving things exist. How much more of this effect will show up in the X5S is unknown.
Win one and lose one. Dynamic range boost of the X5S is nice over the X4S with a gain of another stop, but a slow rolling shutter is ugh!
