RF 200-800mm How to set up dual functionality on the control ring

[mdougc]

The control ring is supposed to be dual purpose - AF and another function that you customize in the settings. Has anybody tried that? I can't get it to do anything but focus.

However, I customized the button to cycle across AF methods. That is really handy.

Great lens - sharp, fast focus even in low light.

Hi mdougc,

Greetings,

The Control Ring on the lens can be programmed to the following functions on the R5.

Set AF<Control>MF switch on the lens to Control

See C.Fn3 for dial programming options

Hope this helps 😀

Thank you!

That's all there is to it?  So it doesn't matter how you program the button.
Why don't they publish a user guide for this?

Also, how did the subject line on my original post get changed?

Not by us. Either the moderator or an algorithm?

If anyone is interested, I finally found the user's guide for this lens on Canon / Australia.
It is not available on Canon / USA.
