I would not agree about Pi camera. It has adjustable focus and they even sell a corresponding tool https://www.adafruit.com/product/3518
Sorry, but a camera without focus is a just gadget, not an equipment...
Another idea then, do you think those “smartphone lens” would work?

Thank you

Hello

Is it possible to adjust focus on the camera? The corresponding lesson on this forum says "don't try to adjust the focus or it will break" - but it makes no sense, this is a camera after all! The camera looks similar to the one from Raspberry Pi, no?

Apart from fish eye, is it also possible to use other lens (with M12 mount adapter for example)? I need a narrow angle one.

Thank you!
