So I followed this video to setup my back button focus: https://youtu.be/vpEGBiIMAZk

The AF with the back button seems different the AF I get in auto mode. In auto mode when I half-press the shutter I get a beep and green boxes. Both are missing when I press the back button AF. Is this expected?

I’m also noticing that the the back button auto doesn’t detect birds as well and doesn’t seem to have any eye detection (even though I’ve got animal + eye detection enabled).

I think I was just shooting in low light so eye detection wasn’t able to do its thing. It was 6:30am. Now it’s past 7 and I can confirm eye focus is working! Although I’m still a little confused re: the difference in AF behavior between auto and back button.

As I said, depends on what you have set the button to do. On my R5, I have set one back button to do spot AF without tracking, and another button to do subject detect tracking mode. That way I can pick and choose what I want

A note - when serving an AF function to a button, you can use info set button to further customize AF parameters. That is how I can do 2 buttons with different AF characteristics. It's sometimes not obvious from manual that this flexibility exists
