No need to get heated! juanmaasecas is correct: The R5/R6 has a bug with non-IS lenses when IBIS is activated. And he has brought it to the attention of Canon and many R6/R5 owners. The bug involves a twisting of the IBIS which shows most clearly in the edges of photographs. This phenomenon only takes place during the FIRST shot after the camera body has powered on or been reactivated after having timed out (or "woken up from sleep").

One easy workaround is to take a burst of shots, examining the first for the phenomenon, and then using a subsequent shot if needed.

Hopefully Canon is working on this! And do note that it is only very noticeable at the slower shutter speeds--but it is EASILY reproducible by anybody with an R5/R6 and a non-IS lens.

To answer the OP, the R6's IBIS is very effective when used with EF lenses--just keep in mind the bug that has been acknowledged by Canon.

Maybe, though I am having some difficulty reproducing the bug. I am probably doing something wrong. Perhaps I just don't want to believe it.

If Canon releases a fix for first shot after power on / wake up only, continuous IBIS only, when using un-stabilized lenses only, blurry far edges at slow shutter speeds I will definitely install it.

And if they never do, well we agree that the IBIS is, at least most of the time, very effective when used with un-stabilized EF (and RF) lenses.
