It would be interesting to learn how many R users actually depend on the control ring on the lens. (Not just imagine it would be nice to have.)
I don't use the ring for my only RF lens (35mm f/1.8). I also have a Viltrox adapter with control ring that is easier to use but I don't use it either. I think that many would like the Viltrox, its much easier to find with your fingers and has definite clicks that are subtle but they do work and you can count them if a click actually translates to some value.

I also have the basic Canon adapter which I do use;)

This is a good piece of equipment for us that can't afford the new RF glass. However, for those of us that have a 70-200 2.8 IS USM L version II lens, in the R5 and R6 manual, this lens is not compatible for the 12 fps speed. Only the version III is. Hopefully Canon will do a firmware upgrade to fix this.
Thanks for the heads up...I’m well invested in EF glass, but it seems I need to inventory what lenses will work well with my canon r6 when it arrives.
money is tight for additional glass, but 12fps is one of the reasons I upgraded.
Hopefully a firmware upgrade can fix this.

Japan.
Ordered the ring control adapter and Drop in filter version back in early July, both have their purposes. Both were reasonable prices back then as well.

I use mine to change between eye detect and other AF modes (primarily single spot). It works really well for that.

I wish the eye detect type was settable via a custom button but sadly it is not.
What body is your information based on? R5 or R6?

When the Shutter Mode is set to [Electronic]During continuous shooting, if the following conditions are satisfied, high-speed continuous shooting (maximum burst of 20 shots per sec.) is performed.

  • The lens is set to maximum aperture except for when using an EF-S lens*.
*For details on the lenses, see "List of lenses that the continuous shooting speed of max. approx. 20 fps less likely to decrease".

  • The continuous shooting speed may change in response to the shutter speed, aperture, aperture status during continuous shooting, subject conditions, brightness (shooting in a dark environment, etc.), type of lens, etc.

Seems to me a list of lenses that will NOT work well would have been shorter...but in any case J's pic should be reassured.
