Since it affects others it can't be incorrect, can it? Maybe Olympus and Fuji have fast enough read out for 12 receptively 14 bits, but the Sony sensors apparently do not, nor does the GH4 which drops from 12 to 10 bits.

You are correct, that it allows Fuji to implement very short exposure times. But the slow read out times make for rolling shutter effects even with very short exposure times.

Rolling shutter is already an issue when bikers pass the scene, or driving cars.

Two rolling shutter examples from the Olympus E-M5 Mark II:

Thee you have a camera shake issue ruining a shot with short exposure time but movement due to the very slow read out.


Then there is the next issue: the inability to sync with flash with (the current) electronic shutters.


Electronic global shutters, which should be the cure, impact low light performance and DR.


Canon, and Fuji together with Panasonic, have filed patents for improved global shutters, so sensor manufacturers are working on solutions.

 

As far as a potential DR drop goes if the supposed difference can't be measured, then it's irrelevant. That's where Fuji and Olympus stands. Unless you have some kind of proof that shows otherwise, again it's just talk. I took test shots with both the mechanical and the electronic shutter. After adjusting the exposure and pixel peeping like crazy, I couldn't see any significant difference. The net result? Electronic shutter on Oly and Fuji doesn't affect DR. Again: this is not the case in some other cameras.

 

I never said rolling shutter is never an issue. I said that it seldom happens in my use of the camera. If you photograph moving stuff you're more likely to encounter it obviously. But the thing is: in real life, it's a rare occurance. I only encountered it a couple of times in hundreds or thousands of shots. Yes, I don't take pictures of moving cars or sports.

Now: have you experienced it first hand? It's easy to find stuff on the internet, but what your hand picked examples don't show is how rarely it happens.
