AF point back focus moving- EOS 6D Mark II

Ipa — Sun, 21 Jan 2024 00:29:54 GMT

i use back button for focus. But the point moves around, so i have to press another button to make it move to the center. Is there a way that it is just centered all the time ?

Thank you. I have the same camera and I also use BBF. There are a lot of options for this, but can get mine to stay in the centre. These are my settings for Av mode, I have different ones for tracking people and animals:
In the Purple (Focus) section:

P1
AF Operation AI Focus
AF Area Spot AF
Whole are track On
Subject detect Auto
Eye detection left but can change
Switch subjects 1
Focus Mode AF

P2 Servo cases: left in Auto
P3
One Shot prior Focus
Preview Disable
Lens drive On
AF beam LED
P4
Touch & Drag Off
Limit AF areas Spot AF
AF area control M-Fn
Sensitivity 0
Orientation link (bottom option in list)
Limit subject Auto
L/R eye detect Off
P5
MF peaking Off
Focus Guide Off
Movie servo Disable (I shoot only stills)
Wrench Menu:

Custom buttons
shutter 1/2 press Metering start
M-Fn Direct AF area select
AF-ON Metering and AF start
* *
AF button Eye detect
SET Set AF to center
Multi controller Direct AF selection

If you want to try this lot out, I suggest you save your current Av settings to C1 mode
Then go into C2 and make the settings above, and save those to C2

Try them out and let me know how it goes.

If you read the list (I have indicated the menu pages and. chapters involved) and follow the menus in sequence doing all of these, then judge the result.

You can configure the LOCK feature on the top of the camera - OFF/LOCK/ON, to disable a selection of controls, if you set the switch to LOCK position. You will find the description of this on P926 of the Advanced User Guide

Make sure you turn off the touch feature and any others that you want disabled. You can experiment with which ones you prefer to disable, and at any time get full controls back by moving the switch to ON.

After configuring what to disable, exit the menu and press the joystick straight in to centre the focus point and then on the top of the camera, move the OFF/LOCK/ON switch to LOCK position.
Then try it out

The ref to the 6DII is in your main title. You can correct that.

Back Button Focus, or BBF, does not control or select an AF point. All that BBF does is engage or disengage the AF system. That’s it. That’s all it does. Your active AF points and AF point behaviors are defined by other settings.

Agreed Bill, I rather left that one aside and concentrated on the focus point configuration, touch screen and control locks to sort the OP out. I use single point fixed AF, which is what she has requested, so I hope this will help her out.
