Focus Mode Switch Auto/Manual by Assigned Custom Button on R5/R5ii

Ive assigned a custom button to toggle between Manual and Auto Focus on R5/R5ii but it does not do anything.

Any idea how to make it work?

Hi Stefanki, welcome to the community here.

It will be a little easier if you can mention which button you have customised and exactly what the function you have selected from the customise buttons, and what lens you are using.

I just tried to use the AF/MF function assigned to the * / AE-lock button on my camera, and it has no effect if the lens already has an AF/MF switch. However for lenses that do not have an AF/MF switch then the button works as you would expect.

Hi Brian,

Ive assigned 'Focus Mode' through the customisation menu to the DoF button (as a test).

Id like to switch between Auto and Manual Focussing during video recording without using the lens switch

In that case I suggest you try the following steps.

Assign "Pause movie servo AF" to the depth of field button. This stops the camera focusing as it would normally do.
Find Electronic full-time MF in the purple AF menus, and set it to ON (Enable).

As a proof of concept I did the steps above on my EOS R6 & EOS R6 Mark II it works. I tried it with different lenses too, EF 40mm f/2.8 STM, EF 85mm f/1.4L IS USM and RF 28-70mm F2L USM. Both bodies consistently can operate manual focus without having to switch the lens when movie servo AF is paused.

Thanks Brian, as a matter of fact thats how Ive been using it but I have two problems with it: As soon as u review a video or go to ur menu for some reason it immediately defaults to movie servo active and very often I forget to pause it again (there is no active sign to remind u its paused only when toggle on and off) and so the battery gets drained incredibly quickly also the AF keeps hunting.

So thats why I tried to assign a specific button to toggle it on and off but as I said for some reason its not working and Ive been through the manual and cant absolutely nothing related to how to use it.

So I guess Ill stick to suggested method for now

Thanks Again

Have you tried programming a button for [AF-OFF]? It would only be effective when you’re pressing it in a way similar to using BBF.
