I use a couple of Canon EF portrait lenses (135/2L & 85/1.8 USM) with EOS R and I don't have any major problems as i keep the shutter speed around 1/200 most of the time. But I was wondering how effective is the IBIS on R6 with these EF lenses. Is it still 5-axis with EF lenses or downgrades to 3-axis?

Some used R6's are popping up here and there and I am contemplating if its going to benefit my STILL images in any way - (No interest in video)?

Thanks in advance

From my point of view, it's amazing. I shot with a Sigma 35mm Art (EF mount, no IS) using IBIS only, 1/6 sec hand held. Needless to say I would never have attempted that with my 5D4.

Why people only look at the Center? Your edges are blurred.

What does your comment have to do with the effectiveness of R5/6 IBIS on this hand held shot?

And what difference does it make if the edges are "blurred"? Why would the image be better if they were "sharp"? Also, they aren't even all that blurry, considering that some of the greenery was undoubtedly in motion just like the water. The point, I take it, was the effect of the slow shutter on the water. And the water isn't really centered.

Not saying that this shot belongs in MOMA, but it makes the poster's point adequately.

Of course it has to do. You can’t be talking about ibis effectiveness and be looking only at the middle. In a landscape style like this, sharpness at the edges is important. And he is using a very sharp lens capable of delivering the sharpness, but then the image is not as sharp as it should.
of course it’s not intended to be a picture for MOMA or whatever, but ibis is just not as good as the current state because it has some bugs. I found out an important bug and it seems Canon us working to fix it.

You know what? You're absolutely right. Anybody who thinks they are going to get a poster-sized print handholding at 1/6 second is headed for disappointment. I was just trying to show that the IBIS works really well for non-IS EF-mount lenses.

Bear in mind also that this is shot at f/3.5, so not much DOF, which means that the corners might be out of focus due to aperture, not IBIS. Me, I was just checking out a local park I'd never been to and thought it would be fun to try to smooth the waterfall with a slow shutter speed. Normally I wouldn't dream of trying this without a tripod, but it seemed like maybe IBIS could be helpful. I think the result exceeded my expectations.

Maybe Canon's IBIS in the R6 is flawed, or not as good as Sony, Fuji, etc, I don't know. This is my first mirrorless camera with IBIS. But WTH for a snapshot like this I think it's amazing, given I'm coming from DSLRs that can't do anything like this, even with in-lens IS.

Canon ibis is around 2 stops better than Sony. 
But there is a bug and yes the Center can be sharp and edges be blurred because if the bug. With a bit of care and knowing about the bug and how to set the camera not to encounter the bug (setting ibis to only for shot instead of always on), you can get a better result still. I can get pin sharp pictures at even slower than 1/6s at 35mm.
