Canon R6 I R6 vibrates strongly during focusing

[GuyTurenne]

I have been using my R6 for several months. I have the Canon RF/EF lens adapter. When I use my 600mm F4 L lens with my R6 the camera body will periodically vibrate very strongly when focusing on or tracking a subject. It happens with the lens alone and more frequently when used in combination with my 1.4x and 2x TC's. It is very annoying when this happens. Is this a problem? Has any one experienced this, knows what may cause this and is there anything that can be done to correct this? This does not happen with any of my other EF lenses.

Guy,

This sounds like it may possibly be related to my issue discussed in this thread:

Technical Question - Focus "chatter"

I have an R6 and I have noticed that when using Servo AF, occasionally, when actively focusing with Servo AF, even against stationary objects that should be easy focus targets, such as high contrast vertical lines, I hear the focus servos hunting (chattering). It seems worse on an STM lens, but...

Not quite the same, but I do not have a long lens, nor an EF/RF adapter, but I imagine the "chatter" i feel and hear could be amplified with a longer lens combo. Sadly, I have not yet found any answers to my issue.
