Arducam LN040 CS-Mount Lens for Raspberry Pi HQ Camera, 12mm Focal Length

No, the LN040 is specifically designed for the Raspberry Pi High Quality (HQ) Camera module, which uses a larger 1/2.3" sensor and a CS-mount interface. The standard Camera Module V2 uses a smaller M12 mount and sensor, so this lens is not physically or optically compatible with that board. You need the Raspberry Pi HQ Camera for proper mounting and image circle coverage.

To focus the LN040, first securely mount it onto the HQ camera's CS-mount thread. Power on your Raspberry Pi and stream the camera feed to a monitor. Gently rotate the lens's focus ring while observing the live image. Turn the ring until your target subject appears sharp and clear. Lock the focus by tightening the locking screw on the lens mount (if present) or by carefully not moving the ring further. Fine-tune while the camera is at its intended working distance.

The F1.6 aperture is a relatively wide opening, allowing more light to reach the camera sensor. This is beneficial for Raspberry Pi projects operating in indoor or low-light environments, as it can improve image brightness and reduce motion blur without requiring higher ISO/gain settings that introduce noise. It enables clearer footage for applications like home security, nighttime monitoring, or indoor robotics where lighting control is limited.
