R6 Mark II focusing frustration

I am attempting to set up my R6MII in the following way:

Back button focus mapped to AF-ON button, no eye focus, smallest spot focus point.

* Button mapped to eye-focus tracking.

I have the star button/eye-focus working fine. I am completely bedeviled by the AF-ON button setup. I have the eye-focus turned off for this button, and the spot focus point appears in the viewfinder. However, when I use the AF-ON spot focus mode it will expand a blue box to grab an area larger (sometimes much larger) than my intended point where I had the point prior to hitting the AF-ON button.

For example, a row of daffodils and I want to focus on an individual flower, the camera will expand the spot focus point with a blue box to incorporate the row of daffodils, I can't isolate the single daffodil.

I want the AF-ON spot focus to work as it does on my 5D3, where I can isolate an object and the camera doesn't take over and expand the focus area. I am sure its a setting in the menus, but I spent a number of hours today and have been unable to get the behavior I want.

Can anyone help me out here?

Thanks in advance!

Try making sure subject tracking is turned off in the menu. That worked on my R7 to isolate that spot focus point. Then you can map a button to activate subject tracking when you want it.

Yes, that's the culprit. As long as you have "intelligent" subject tracking on, the camera will try to find a subject for you, not just be constrained by you selecting a too small AF point. According to the camera's judgement, that is.

Thank you!

Thanks!
