Posted this on another thread but applicable here. imho

I used to use an A1U and it had "Rolling Shutter"

I looked for the footage but was not able to find it.

Simulate the footage by selecting the highest shutter speed, 1/10,000 for A1U. Drive down the interstate in the fast lane at or just above the speed limit, 75MPH or so. Frame the oncoming traffic fast lane perpendicular to the flow of traffic. A box truck or semi-trailer would be noticeably slanted. I found it disturbing.

Would be nice to see someone with an EX1 do this trick. Maybe shooting out the window of the driver's side backseat would be wise.
