EOS R5 II issues with RF lens IS (wobble/tick/shift)

[Strill]

New R5 II with IS enabled on RF lenses has an issue while filming in video mode (all codecs, frame rates, and resolutions). 

I've tried 15-35, 24-70, 70-200 (2.8 RF) and they all shift/wobble/tick when moving or while holding relatively still (beyond the normal drift/slight wobble from typical lens IS)

The issue does not exist on the original R5 and wondered if anyone else had this happen with the R5lI.

I’ve also changed batteries, reset the camera, disabled all in camera ibis, but the issue persists until I turn off IS on the lens itself. In photo mode it does not seem to be an issue at all.

are you using a gimbal? Gimbals and IBIS never play nice together. If using a gimbal, try to see if you get the same issue handheld.

IBIS is not the digital equivalent of a physical gimbal stabilizer.  

What subject is the camera supposed to be tracking and locking into focus?  You’re moving the camera around everywhere.

Canon sent it in to their engineers and sent out a new replacement that does not have the issue. IBIS was not on at all (sample was shot in canon RAW). It’s an issue with the body communicating with any RF lens. The issue happens on a tripod or while holding very still.
