To disable autofocus using v4l2-control:

/usr/bin/v4l2-ctl -c focus_auto=0 # turn off C920 autofocus.

Is it possible to make these settings permanent? After i rebooted my raspberry pi everything was gone.

You might try...

sudo nano /etc/rc.local
# --- Skip down to the line right before the ending line
/usr/bin/v4l2-ctl -c focus_auto=0
# ---

I was able to uncheck the autofocus box when using the "camera settings" plug in.

Hello @sporte77 !

Nice, but you reactivated a two year old thread with referencing to a plugin that is somehow only one year old...

I have to be honest, I found the plugin suggestion helpful, so I'm glad they posted it. Pointing out it wasn't available at the time solved nothing.
