My apologies. I'll still note that there are no good examples of any modern Canon lens with "focus shift" problems that weren't quickly resolved in formware, virtually undectable in normal shooting, or both. Nothing posted yet on this thread but the hyperbolic "concern".
Have you reached out to Canon support? I got an “Error 70” msg while my camera froze from using animal eye auto focus. Had to send my R5 into Canon and they replaced the circuit board!Received my RF 100mm macro from Adorama last week. I had placed a preorder pretty much the moment it was announced.
Optically, it's pretty amazing, though I must confess the only other macro lenses I've owned are a couple of Nikon DX format. The stabilization is amazing. With auto-ISO allowing up to 25600 on my Canon R6, I can easily get handheld shots that always came out blurry with the Nikon with "VR2".
But 2 things seem a little off. Hoping for some feedback, as I'm pretty new to Canon. Got the R6 only a few months ago.
The RF 100mm macro lens seems to always make a slight whirring sound, as if a motor or tiny fan is constantly spinning inside. The sound is constant as long as the camera is on, even when just sitting still without any use. It can only be heard in a quiet room or if you put your ear right near the lens. Is this sort of thing normal with Canon lenses?
The other problem is occasionally I've getting "Error 70" from the camera, with a message I need to turn the camera off and back on again. Looking this up seems to say it's a problem with the lens. The only other RF lens I have is the STM kit lens which came with the R6, and I don't get Error 70 with that kit lens.

Do you have continuous AF set to enable in menu?Received my RF 100mm macro from Adorama last week. I had placed a preorder pretty much the moment it was announced.

IS is on when the viewfinder is active, it will stop when you are in the menus for a while or when the camera goes to sleep.[..]Does it make the sound all the time when the camera is on?[..]
Just like me (the use part). I use my EF100L rarely so no point. I also use it on my 5DIV mostly so it stays that way.I ordered it within minutes of the announcement but about a week before it was released, I realized that I had not used my EF 100L in almost a year, so why was I replacing it with another that would not get used. I cancelled the order, if I start using my 100L again, I can always get the RF. Now, I'll see if they have a fix for the focus shift. I'd think that with the smart lenses they have now, they could do it in firmware but it could be more complicated for macro distances and with the soft focus adjustment.
As far as I know you cannot focus stopped down. Camera always focuses fully open (in this case at 2.8) and it stops down during exposure. So focus shift is always there (at f/8 for example).Am I correct in assuming the focus shift issue only occurs when for instance you are focused on something at say, f8, and if you change aperture setting the focus will shift ? I generally speaking set my aperture for macro and take the shot /shots . If I were to change aperture I would refocus and take the shot/shots
IS is on when the viewfinder is active, it will stop when you are in the menus for a while or when the camera goes to sleep.
I didn't realise "focus shift " was the same as back/front focusing , back focusing in this case. My RF 70-200mm f2.8 had the same issue but was quickly fixed in lens firmware update, I would sincerely hope Canon will provide a fix ASAP, it wasn't a major issue on the 70-200 but it certainly will be an issue on a Macro lensTook the lens back, will maybe check out another copy when inventory is available. Here is another example, 100% crop, R5 on camera stand, F11 - top shot is RF and bottom is EF with adaptor.

If I recall correctly, there's a 30s or 60s time-out when using the menus. A better test is using the IS switch in the lens, that should disable both IS and IBIS.The lens definitely keeps making the same whirring sound when I go into menus. No discernible change (at least to my ears) when going in and out of menus.
It does stop making the sound when the camera goes to sleep, or when I switch it off.
