To focus the camera to a specific point, simply use the Camera's focus(...) function:

await camera.current.focus({ x: tapEvent.x, y: tapEvent.y })

The focus function expects a Point parameter which represents the location relative to the Camera view where you want to focus the Camera to (in points). If you use react-native-gesture-handler, this will consist of the x and y properties of the tap event payload.

So for example, { x: 0, y: 0 } will focus to the upper left corner, while { x: VIEW_WIDTH, y: VIEW_HEIGHT } will focus to the bottom right corner.

Focussing adjusts auto-focus (AF) and auto-exposure (AE).


focus(...) will fail if the selected Camera device does not support focusing (see CameraDevice.supportsFocus)
