I don't run in to distortion often on the R5 and I shoot the e-shutter exclusively. Hummingbirds definitely showcase it, but the only issue I find myself looking out for is the wing tip banding. Its generally so faint that its not worth worrying about, but you should still be on the look out.
In common use for BIF it’s extremely unusual to see any rolling shutter with the R5 except when shooting small fast birds. In my experience it usually manifests as banding in the wingtips such as this example at 200%

I have seen that ES effect before too while photography small fast birds. Thankfully, it's not too difficult to fix in post.

Again, I have to qualify my comments, it is extremely unusual to encounter rolling shutter with the R5 for wildlife even while panning. I've had to dig through nearly ten thousand images to find a couple of examples and they were all in smaller, fast birds. At normal magnification, it isn't too prominent and one has to search for it. Obviously, with cropping and pixel peeping it is evident. The sports issue is entirely different and I never shot in ES with sports.
Out of curiosity, what is your favorite approach to fixing it other than blur or careful retouch?

Fast moving baseball bats have bent a bit backwards for me... and baseballs in (extremely fast across frame) motion have a bit of line-by-line pixelation. Eshutter makes flickering lights into strange background bands and makes backgrounds with straight lines tilt a bit if panning.
If I had newer big lenses, I would shoot 12FPS EFCS shutter more often. As it is, 20fps with good frame rate in EVF vs 7ish with my older lenses with more VF jumpiness isn’t much comparison. I have used Eshutter without much reservation for sports without extremely fast motion... Basketball and dive worked really well for me. Baseball and softball, not as well...

I understand what you're saying, and I agree. It's extremely unusual to encounter the rolling shutter effect with the R5. I've only seen it in my photos a handful of times, and each time I've been able to make reasonable edits to fix any issues.
There is no way around "fixing it" other than blurring or careful retouching, unfortunately, when it does occur.
As to my editing method: I create duplicate layers in photoshop, and add a gaussian blur to the top layer of the image. Then I create and invert a layer mask and "paint" the blur in around the wing tips using my Wacom tablet. I find this method doesn't take long or create much extra work, especially when using my pen tablet. I can get quite a natural look from this method, too.

Checkout this video by an very good Australian bird photographer who has been using the R5 extensively. This is on the very topic of R5's e-shutter and whether it is suitable for action work. Short answer it is indeed usable in many cases.

This is an excellent video. One major factor Jan overlooks though in explaining the factors that affect whether rolling shutter artifacts will be visible is in the size of the subject. When we speak about sensor scan speed we quote the total sensor scan rate. That's material for subjects which take up the majority of the frame, such as buildings during a fast pan or telephoto closeups of action. There are many scenarios where subjects occupy only a small portion of the frame, such as a bird. In those situations the effective sensor scan speed is much faster, as in the amount of time it takes to read the subset of sensor rows occupied by the subject. For example, if the full sensor scan rate is 1/60, the scan rate for a bird occupying only 1/5 the frame is actually 1/300. Even more specific, the number of sensor rows in which fast action is actually occurring (wing movement) is a smaller subset of that subset.

Thanks for bringing that up as it is a really important point that many don't realize. I didn't fully understand that till sometime last year.
I think I've mentioned in a few posts that I can get the A9II to show distorted hummingbird wings and the way I get that to happen is when I fill almost the entire frame with the hummer. Of course in 99% of bird photography the A9 won't distort anything. Same goes for the R5. Exactly why I've said from the beginning that my biggest issue with the R5's scan speed is the leaning vertical lines of grass, reeds and trees in my background bokeh. Not too often with bird's wings because I'm often only filling a small portion of the sensor with my birds.
