Full Walkthrough: Setup RPI4 take 64mp photos and Control Focus

It is very detailed, amazing.

Continuous autofocus employs motion detection so you can try to move the scene.

You can also try single focus to see how it works, but as we said in other threads before, the effect may not be so good for a 4-eye camera, because it is based on center focus.
