The update gives me ERR 70 trying to update with a 5D-IV :-( I tried with two different SD SanDisk cards formatted in camera (SDXC II Extreme Pro 64GB and SDXC I Extreme Pro 512GB).

I had to reset the camera putting out the battery to recover the camera functions.

SOLVED 7 nov: I tried again with an old SD card (SanDisk Extreme Pro SD HC I 16 GB) and the firmware update worked flawlessly.

Thankfully mine updated ok, from an M6 Mark II.

I had one of the first copies of this lens and I always had issues with the IS jumping and dust behind the front lens.

I sold it and switched to a prime lens, but Canon really took long to figure out the issues.

So yeah, the 5D3 does have the ability to flash the firmware on lenses. You don't see it until you open the menu item for the camera firmware, and then its there. Now I know. Still probably going to follow the advice that since mine is not broken, I won't fix it.

I think the update is for using it on the R5.
Well, like the above posters, mine works flawlessly on my 5D3. However, please share your source, I have not seen any particular body mentioned in the few places who announced it such as TDP.

I haven't seen any problems with this lens mounted on my 6D Mark II, so I to am wanting to know if this a problem with the R system bodies. Of course I'm planing on getting the R5 down the road.

As I posted earlier, my copies have had 0.0 problems on 10s and 10s of thousands of shots on a variety of bodies. There are reports on forums of IS jumping of the 400mm DO II and other lenses on the R5, which is why I suspect the upgrade is directed there.
