Electronic shutter woes - not many

you did well,
Thanks
only comments are 1) you would benefit from 400mm,
I'm sure I would. If Olympus cares to release one that would not ruin me, I'm in.
2) I'm surprised with your happiness with the electronic shutter, I tend to avoid it because of rolling shutter fear but you seemed to have proved it is OK on the EM1-II.
Yeah, I was a bit hesitant at first, but after some shooting it became clear that it will not be a big issue.
However, In my effort to try to find the limits of what I could do, I managed to get some samples that were clearly affected. So as promised in my OP, a little analysis follows.
This looks good until you notice that the spaces between propeller blurs are not exactly the same. Most people would probably not notice this.
The propeller is still quite blurry, but this looks a bit more iffy and probably a lot more people would notice that something is off. Still, not THAT bad.
Ok, this is so obvious that anyone would notice.
Conclusion? You're fine as long as you're able to nicely blur the propeller. How much will depend on how big part of the frame the propeller end up taking. In the above example, the plane fills the width of the frame almost completely. So it's close to the worst case scenario. For planes in the distance that don't fill the frame, it's not an issue at all.
Now, for helicopters.
Can you tell anything is wrong here? Looks good to me. I guess the rotors of big helicopters don't move fast enough.
Ultralight copter. The rotor is smaller and rotates faster, and it shows up in this bendiness caused by rolling shutter.
Faster shutter speed, you can still see the curvature to the blades cause by rolling shutter.
Conclusion? Not an issue for bigger helicopters with long rotor blades. A small issue for lighter copters with higher rotation speeds.
And finally, panning action.
Now, this is not a jet, so the panning wasn't super fast, but you can imagine the plane was not exactly hovering over the ground. It was still a fast moving object. Lack of horizontal structures going through the whole height of the image helps of course. But if there were any, I would not bother taking (or using) the shot. So this is kinda the best I have in terms of panning.
Conclusion? Panning is not a problem for airshows like the one I attended. I would probably be for something like Air Bull Air Race, where planes pass the poles at insane speeds. Oh yeah, for that, electronic shutter would not do, even as fast as the one on E-M1 II is.
Note: none of the photos above were processed in any significant way. Those are full frames scaled down to not waste bandwidth. Raw conversions with my default starter setting. The last one was straightened up to make evaluation easier.
