Image stabilization panning detection in RF lenses

From what I've seen so far it appears that the RF 800/11 (and similar) don't have an automatic panning mode. Maybe other owners can chime in here.

I too have had (panning) images ruined by the IS even at very high shutter speeds (even using Mode 2). I actually get a higher keeper rate when I turn IS off completely (R5 + 100-500 +/- 1.4x), but I have to admit that I'm pretty darn stable when swinging the camera (and a heavy(ish) lens helps here too). Others' mileage may vary.

Experimentation is the best way to determine one's own capabilities. Kudos to you!

Be sure to post back with any more findings!

Tried RF 800/f11 with R5 on airshow. This lens definitely does not have panning detection. Most of my panning shots with IS enabled have been ruined (still background with blurred subject). Disabling IS helps drastically with shutter fast enough.

Quite different results with RF 100-500 (and RF 1.4x) on R5 with IS mode set to "2". Almost all shots are sharp with correctly blurred background. Just for test switched to "1" mode with effect almost identical with RF 800.

I guess that this mode switching is much more important with IBIS as scope of sensor movement can compensate for really long panning shots - destroying them if not in mode "2". This also looks like that the only way to enable panning detection on IBIS is to have lens with that mode.

Br, Pawel.

How fast were the planes flying and were you using electronic shutter or electronic first curtain?
I've noticed with videos the panning with IS ON can be very inconsistent. Sometimes it works just fine if I am panning at a steady pace, but other times it exhibits a "stop and go" behaviour indicating the IS is working against my pan.

Here is another example, the duck was swimming fairly quickly but after a few shots with IS on I realized it was causing blur and working against my panning. Turning off IS helped and I had more shots that looked in focus, but it was really with the low light and low shutter speed (1/400) and up close most of the shots had a subtle motion blur.
