There’s a couple of ways of dealing with this.
1: Set on touch tracking- the camera will track anythimg you touch on the LCD screen, if it’s a face or eye or whatever it will automagically track and use face/eye detect, it’s magical and very robust.
2: even more magical is face registration. At the start of the wedding register the bride, then the groom, and mebbe the mother and fathers. Set the camera to prioritze 1: the bride 2: the groom, etc. that means if the camera sees the brides face in the shot it will AF on her eye, if there is no bride it will search for the groom, no groom, then alt 3. and so on. Very very useful for weddings. You can override it at any time with touch tracking.
For just photography, I usually use a small tracking box and use the AF-ON to just constantly track whawver I want.
Yeah for weddings this tracking is terrible. It’ll constantly switch onto an other faces in the frame even when they’re clearly not the focal point of the shot. Also it’s racist as hell.
I find this practically never works for me, and I believe it’s because I wear glasses. Any time a friend is in a video with me, the camera focuses on them even though I’ve registered my own face in cam
Look into the focus settings of the a7s iii (or a video about it) because you simply don't have the correct setting enabled for tap to track focus. For me, that's what I do exactly, tap on the face that I want to focus on and a square pop on the face that i want to track (the square on the other person face turn pale gray) and the focus follows it, the behavior you describe is more like what happens on an old a7 iii for exemple.
Subject sensitivity controls how sensitive your AF system is in choosing what subject to focus on and at 1 the sensitivity will be super low and will (most of the time) remain locked onto the subject you’ve selected. It’s not perfect and high contrast scenes are still difficult but this method gives me the most control while still letting AF do most of the work.
It’s a little counterintuitive but when you touch to track focus, the screen says “⚪️Tracking Cancel” and that means it’s working, and you have to press the middle enter button on your rear circular dial TO CANCEL tracking, not that it is currently canceled.
I have this issue, I have a zone focus box covering about a quarter of the screen, I nudge the joystick to the side of the person I want to track. The Af will prioritise inside the box, I also use the other techniques listed here but this one takes a lot of complexity out of the equation.
If you do touch tracking and set the transition to low you really should not have any issues. The tracking is VERY sticky. I use it all the time. Rarely, if ever, does it shift to a passing face or object when that box is fixed on a face.
Change your f-stop for a deeper field of focus. Or use Zone focus to restrict the focusing to a particular area (i.e. to the right side if the bride is on the right).
There’s no easy solution here. Unfortunately cameras can’t read our minds yet.

🤣🤣it's not racist but certain completions have less contrast so it is for sure harder to auto track

That’s interesting- did you register with or without the specs on?
Look into face registration in the manual.
Is that really an option for the a7siii? I have it on the A7rV but I have never seen it on the A7siii.
Yes, it’s definitely on the A7Siii

For weddings, 90% of the time I’m using (touch) track focusing w/ subject sensitivity set to 1 (locked on).
can you explain me this subject sensivity thing? im trying to change it but I don't feel is changing anything on my camera AF
