In the camera settings of DJIGo4 (IOS) you can turn AFC mode on/off. I can find no reference to this in the manual or anywhere on Google or even this forum.

Can someone please tell me not only what it does, but also what it stands for. Obviously it has something to do with autofocus, but what exactly?

I thought of asking DJI support, but they would only ask me to reinstall the software and then send them a video of the problem.

AFAIK it will automatically focus when you start recording without having to tap the screen.

I'm going to answer my own question. It stands for Auto Focus Continuous. Turning it off would appear to stop the camera from constantly autofocusing.
That's a great behaviour, as I can focus once and forget about it.

Is this only on the iOS? I don't see it on the Android. Can you please explain where you see this mode?

I just noticed this as well after the upgrade and yet again having to set various settings that get lost on update (DJI fix this)..

Anyhow I had it on (its on by default) and was just resetting up some lost settings where I heard the camera constantly auto focusing with this setting on.  I'm not sure how much of a good idea this may be when flying because if it see's different things it wants to focus on you may in your video see blurriness.

I'm not sure yet how I feel about it until I do a few flights..

Thoughts?

It is in the main camera settings.

It's on Android DJI GO4, as well.  I just noticed it in a flight a half-hour ago, as my phone was doing the double beep thing and the green square lighting up every so often. I was looking to see if I was hitting a control, but no - it's actually real autofocus!  Great add that I wasn't aware of!!!

I believe so. I tried AFC and it would beep when focusing.

It only seems to "AFC" whilst NOT recording (Android). It doesn't focus again unless I stop recording.

You want this, otherwise it will continually seek focus during recording.. Eg a bird flying past close by will make the background lose focus (blur in and out). If you want to change focus during recording then use "tap and focus" (turn off AFC and switch to AF).

You should look into Focus Peaking and using manual focus to create some stunning depth of field footage.

Actually, I'm pretty sure we can still also tap to focus while it's recording in the new AFC mode. There's a notification that comes up on my screen saying something like that, but I'm not sure if I've actually tried it myself.

Well yes, agreed. Just confirming the functionality.
