The official camera modules have fixed-focus lenses, which are either glued or need manual adjustment. However, Arducam thinks that your focus matters and has released this motorized focus camera for Raspberry Pi. This Arducam camera module is designed for you to control the focus on a camera for Raspberry Pi via software, so you can see closer and see where you want to see.
To learn more about autofocus with Raspberry Pi camera modules, we recommend you read Raspberry Pi Camera Autofocus: The Complete Guide.
