EOS R5 Mark II Image stabilization horrible with jumps and "click" sound

[Eloy]

Hi everyone! How’s it going?

I have a question about stabilization.

Is this normal? Personally, I don’t think so.

In these examples, I’m sitting down, trying to stabilize the camera as much as possible, and this is what happens.

As far as I understand (correct me if I’m wrong), the lens image stabilization is supposed to be turned off when recording video. I’m not very sure if Canon has changed something so that the IBIS in the body and the stabilization in the lens work better together now. The moment I turn on the lens IS and the in-body stabilization, the camera produces a horrible stabilization, with jumps and a very noticeable “click” sound.

I’ve used both a 24–105 and a 70–200 and I get the same result with both.

I have updated firmware and still the same

What do you think about it?

Thanks, Stevet1, for the explanation. I used to shoot with the R6 Mark II, and I never experienced this. I regularly recorded handheld at 240mm without any issues, and after post-production stabilization, the footage was totally usable.

My main concern is the small “jumps” the camera makes while trying to correct movement. I understand that the camera is compensating for the tiny motions of my hands, but these corrections feel very abrupt.

Do you think this is normal? To me, those jumps seem excessive.

Elroy,

What frame rate are you using, and is your shutter speed 2X your frame rate?

Just as an experiment, try a different frame rate.

After several tests I think that movement comes from the IS lens. Basically the lens is trying to stabilize the images and that is why you can hear and see that. 
I don't know what else could be

Elon,

You could very well be right.

“ My main concern is the small “jumps” the camera makes while trying to correct movement. “

This is why I asked you about the AF settings.  The “problem” is the camera is trying to track a subject.  The issue becomes more acute when you are panning across a landscape.  What is the camera AF doing under this scenario?  It’s confused.  That’s what. 

One last comment about image stabilization. The primary purpose of IS is to present a stable image to AF system and the viewfinder.  When you are shooting stills, the IS spends well in excess of 99% of its time doing exactly that.  The shutter fires in a VERY small fraction of a second. 

Keep that in mind when shooting stills or capturing video.  It’s not a substitute for a mechanical gimbal stabilizer.  Trying to use IS like that is what causes people problems.
