Can Canon AF do real time tracking of objects (not just faces,eyes,cars,animals etc)?

A really quick test from me.

Some additional hints:

- This is not a scientific tests
- Speed and jerkiness may vary
- Some tests are not that fair (e.g. sometimes I brought the subject out of the frame briefly)
- I did it once and used a longer sequence (to show that it was not cherry picked / spliced)
- I accidently took some snaps with the Nikon, this is why the screen turns so bright (smartphone tries to adjust) -> used the R5 too much, no longer used to the Z6 shutter.
- Nikon Z6 first (00:00), EOS R5 second (1:26), EOS R last (3:33)
- Sorry I don't have a way to record the HDMI out, had to mount a smartphone to the flash hotshoe, quality isn't the best
- Originall I didn't want to test the EOS R, just did it for fun first, but just had to document the "level of performance" -> My setup was already compromised though (some changes made / some elements missing in the background)
- Min shutter speed on the R is different, overall ISO and shutters speeds are not identical, cameras were left on automatic (AV + Auto ISO + Auto Shutter speed + Min Shutter speed)
- Take all of that with a grain of salt
- In my opinion the Z6 has the best user interface and the best results, R5 was quite good in some scenarios but struggeled in others (e.g. on the wood sticks or when the subject is leaving the frame briefly, R didn't perform too well
- I noticed that the flip out screen of the Rs introduce more roll when looking at the screen and zipping around the sceen
- Remember that this is the original Z6 that is same gen as the EOS R - night and day difference (Z6 has the better eye detection too, unfortunately the AF is as slow as that of the R)
- In reality (and even on my screen capture) the R5 looks much smoother than the Z6 (their update rate of the AF box is not that high)

And now someone please do a comparison between any of the older gen Rs (R6, R5) and the later gen Rs (R7, R10, R3, R6 II).
