I’ve been using haida CPL on the EF 100-400mk2 and canon drop-in CPLs for the EF teles with no issue. Do you have examples to show the problem? What AF mode and what did the camera focus on?

I'm using the EF 24-70L on R and R5 and get good results with both. However, for live music and stage events generally, I get better results with prime lenses (all still EF). Where is the R falling short? Lighting can be challenging and the R6 may well have an edge, not only with eye-tracking which will work well went the talent is well lit, but also the people object tracking which will keep the focus on the head even when the eyes are not lit well.

I've read that the AF works better with RF lenses than EF but have no personal experience with RF lenses. In normal well-lit conditions, I'm getting close to 100% keeper rate using adapted EF lenses. In difficult conditions, it's less although better than I manage with DSLR. I've checked the stats for a recent difficult stage show with fast action, complex lighting, haze and fog where I used R5 with people detect and eye-tracking and 1DXM2. The keeper rates, combining the AF performance as well as my own performance for timing and composition was 65% for the R5 and 30% for the 1DXM2.
Love my R6 -
Not in Al Servo as far as I can tell?
Maybe they will enhance options in futureAh, you are indeed correct. Only when the AF point is set to face detect rather than spot.
I didn't realise that--a tad annoying!
and after the trial Canon offer you a 5% discount- though I guess you could find better prices elsewhereYou could always try Canon’s 48 hour test drive before you commit and then decide if it’s worth upgrading for you.

I haven’t used the R, but I got the R6 on test drive and the eye AF was genuinely like witchcraft.
Good to hear your personal experience, thanks for sharing. Also reassuring that your 1dxii lunches a load of images - it's not just me!
I switched from a 5Dmkii to the R5. No regrets and I am sure I am only using a fraction of its functionality and capability. I’m the limiting factor not the camera!
Really good to hear, I've years of experience in being the limiting factor, so it's good to know that will continue to be the case. Very much looking forward to the improved AF, I've heard very good things
Haha the 1DXM2 is still a great camera. This example was very challenging in a theatre with lots of movement, rapidly changing light levels and color, spot lights a lot of red, fog and haze. In good lighting conditions my keeper rate is more like 85% which I thought was great at the time. The R cameras have taken it to another level.
That's good to hear! I do love my 1dxii - but amazed that modern cameras are even better!
but it made a difference today. My camera is now set up so that I can always manually focus without having to alter the switch on the lens. It came in handy when I came across this kestrel having it's lunch on the cliff top. 
I’ve done the same. Tried the R6 and 24-105mm f4 and ended up in the process of moving from Sony. I’ve just put myself down on the RF 14-35 f4 as I’ve been waiting for that to become available. I’m also thinking of trying the EF 400mm f4 in the autumn but really unsure as that quite an expensive lens to buy. The test drive can potentially get expensive! Great marketing tool by canon though. Really surprised other companies don’t do it (I think olympus do).
I initially moved to Sony when they were the only mirrorless full frame option. Times have changed since then with both Nikon and canon joining. My main issue was I wanted a faster long lens than the 100-400 which didn’t many options. The Sony 400 f2.8 was too large/heavy and too expensive for me and there wasn’t really any other options available. Older EF canon lenses are supposed to work well on the RF cameras so give more options in my price range. I’ve still not decide which way I’m going with a faster lens.Interesting that you moved on from Sony to the bright side .........
I was on Sony camp while waiting for Canon to do something on their mirrorless after the R and RP fiasco. The Sony 400mm 2.8 was fantastic lens I handhold most of the time when I was running a workshop in Japan. Now that Canon has substantiate answer with their R5, I sold my Sony lot. Time for Canon to bring out those DO lenses! I envy Sony 200-600mm and Nikon's 500 PF.
I have the RF 100-400 and I have been very surprised by how sharp it is. It suits my needs well. I mainly shoot aviation, however I have shot some wildlife with it with great success (no BIF yet though). The cost was a factor (I’d love the 100-500L but can’t afford it right now) as was the weight - it’s a very lightweight lens. I’ve never owned the 100-400 MkII, but I did own the MkI many years ago. It’s hard to compare as I only used it on a crop body, but I’d say they were close. The MkII gets great reviews though.
