Arducam LN045 C-Mount Lens for Raspberry Pi HQ Camera, 16mm F1.6-F16

No, the LN045 is specifically designed and optically optimized for the Raspberry Pi High Quality Camera (HQ Camera) which uses the larger 1/2.3-inch IMX477 sensor. The original Camera Module v2 uses a smaller sensor with a different mount and would not be compatible without an adapter, and even then, severe vignetting would occur due to the sensor size mismatch.

First, unscrew the default lens from the HQ Camera module by turning it counter-clockwise. Screw the LN045 lens onto the camera's C-mount threads clockwise until snug. To focus, point the camera at a subject approximately 0.5 meters away. Loosen the focus lock ring (if present), then slowly rotate the main lens barrel while monitoring the live video feed until the image is sharp. Tighten the lock ring to secure the focus setting for your application.

The adjustable aperture (F1.6 to F16) controls the amount of light entering the lens and the depth of field. A lower F-number (e.g., F1.6) allows more light, ideal for low-light conditions, and creates a shallow depth of field (blurred background). A higher F-number (e.g., F16) reduces light, increases depth of field (more in focus), and can improve sharpness. Rotate the aperture ring on the lens barrel to select your desired setting based on lighting and creative needs.
