EOS R5 Mark II: What are the autofocus areas with the padlock icon for?

[Bazsl]

The last four autofocus areas are identical to the first four except that the last four have a padlock icon? How are the areas with the padlock different? I can't find anything in the user guide or on line. Thanks.

Sorry. I should have said I am using an R5 Mark II.

The AF areas with the padlock are the same as the ones without except whole area AF tracking is switched off. This means that the AF point will stay where you put it and not follow the subject.

Canon has a helpful AF settings guide that explains lots of the AF settings

Thanks for the reference to the AF settings guide. I missed that.
