Noticed the EF400 F2.8 III and the EF600 F2.8 III also have firmware updates.
No mention of R5, R6 or IBIS

Firmware Version 1.1.3 incorporates the following enhancements:
・Focusing performance has been improved when using the Servo AF continuous shooting mode.

I updated the firmware on my lenses and the EOS R. Worked flawlessly without any issues. Thank you for the help.

Computer updates can be risky at times but at least I can reformat and reinstall from scratch. Cameras and lenses, not so much if the update process screws up. Kinda makes me nervous there are so many updates for the R series when its still so relatively new.

Not an EOS R5 owner in the near future but even so I have updated my 4 RF lenses. Also, I updated my EOS R. So here is your guinea pig
Everything went smoothly!

Have you noticed any improvement in the IS with you EOS R? I thought these updates were solely for EOS R5.?

Will it be necessary to update R5 with said RF lenses on even if we update them with R (which I have)?

No, Lens firmware is applied universally.

I haven't applied it yet, but the lens firmware is specific to the R5/R6. But the R/RP firmware gets you a few new options plus covers you for the new glass that's coming.

Thanks for both your responses to my queries.

Just to clarify... the lens firmware 'changes' is specific to the R5/R6... still good for any camera though.
