Yes, I have reported a similar issue here: https://www.dpreview.com/forums/thread/4641558

Here is a chart I updated that I used when determining if the 100-500 was worth upgrading from the 100-400. The grey boxes mean full use of the camera's sensor and the white would be the resulting ...

I have an R5 (R7 would be similar) and found that using the animal eye-AF and servo works great.   I nudge the focus manually to get it close then let the camera take over with auto-focus.

Make sure you are not using IS mode 1 and don't have initial-focus point set to something small (allow camera to find the subject). Try electronic shutter (with risk of rolling shutter, of course) ...

That is around the same shutter speed I have been seeing issues on the first shot of a series (thread here: https://www.dpreview.com/forums/thread/4641558 ) Basically, the image jumps for the first ...

Somewhat so.    In the images I posted at the start of this thread, I took in attempt to get an example in a controlled test.    It was able to reproduce it on my first try. I am running FW 1.52 ...

I have a similar thread here but using 100-500 on an R5: https://www.dpreview.com/forums/thread/4641558

I found that while holding the lens with my left hand, my pinky finger sits near the focus control ring. If I need to bring focus closer to force the camera to retry, I pull the control ring down ...

This could be related to an issue I have observed: https://www.dpreview.com/forums/thread/4641558

After having played with this for a while, it is not isolated to the 2x, just more evident when using it. I see the issue with the 1.4x or just the bare lens. In each case, the issue occurs at the ...

I have seen the issue with photo - thread here: https://www.dpreview.com/forums/thread/4641558 I can see the image in the viewfinder clearly jump at first photo (not always, but often). The 100-500 ...

Yeah, my 100-500 is on 1.1.0, so not that.

I just added a 2x extender to my 100-500 having loved the results with the 1.4x. I have only taken 39 photos with the combination, but 6 of these had blurry first images in a small sequence (1-3 ...

I seem to almost always place the RF lens cap in the wrong orientation - have to take it off, rotate 180 degrees and retry. They are like the USB of the lens world

I observed the same behavior - my 100-400 II was much more tolerant about using the wrong IS mode (I left it on Mode 1 and panning had no issues).   The 100-500 works great when you select the ...

I had a lockup with the 1.5 FW - my 4th lockup in the year I've had my R5. I was using animal Eye AF with the 100-500+1.4x (was 100-400+1.4x for other lockups).

Absolutely, for me. The R was a love/hate relationship for me.  I loved the images, but coming from 20D/7D/7DII I was used to the button/wheel layout and really missed it when I had the R - it was ...

I just got mine (yesterday) in 3-days from Best Buy.   I had an Adorama back-order for 6 weeks that I just cancelled.   Someone on the Canon Rumors pointed out that Best Buy had them (looks like ...

I went to a birding event the other weekend, starting before dawn.  Instead of a spotting scope, I used my R5 to both identify and photograph the birds I saw. One of the benefits of using the R5 is ...
