I mainly shoot birds with my Z9 and Z6iii cameras. I have the main selector/OK button chosen for centering the AF-point which very often irratically without intention changes position ( not due to tracking mode but of some unintential pressuring) . I often shoot in cold weather and my gloves on and correcting the AF-point from one edge to the middle is sometimes impossible as the OK button is to small. I have earlier had the AF-point fixed to the center ( deactivated the OK button) but cannot find now how to do it in the manual. Another way would be to sign another more accessible button ( Fn-button for instance) to center the AF-point and use the 4-way selector (if necessary for ex. shooting landscape) to change the position of the AF-point. Pls advise, this is really annoying.
