Topic: Deep Focus on an iPhone Camera?

I currently use an iPhone 13 Pro connected to Stop Motion Studio Pro for my brickfilms. I can get crisp shallow focus but so far I haven’t found a way to get a greater depth of field.

This has resulted in the background and even nearby figures looking quite blurry even if they’re only a few studs further away from the camera than the figure in focus.

This is fine for close ups, but on wide shots I want deeper focus to showcase more of the action and the set. Can this be achieved with an iPhone, or do I need a DSLR?
