Arducam LN046 C-Mount Lens for Raspberry Pi HQ Camera, 16mm F1.4

First, remove any existing lens from the Raspberry Pi HQ Camera module by unscrewing it. Align the C-Mount threads of the LN046 lens with the camera's lens mount and gently screw it on clockwise until snug. Avoid overtightening. Ensure the camera is powered off during this process to prevent damage. The lens should seat flush against the camera housing for optimal optical alignment and to prevent light leaks.

Mount the lens on your Raspberry Pi HQ Camera and connect it to your Pi. Open a camera preview application like 'libcamera-hello' or use Python with Picamera2. Rotate the focus ring on the lens barrel while observing the live feed on your monitor. Turn clockwise for closer focus and counter-clockwise for infinity. For precise focus, aim at a high-contrast target. The minimum focus distance is 0.2 meters. Lock your focus by not touching the ring after achieving sharpness.

No, the Arducam LN046 lens features a manual aperture ring only. You must physically rotate the aperture ring on the lens barrel to adjust the F-stop from F1.4 to F16. There are no electronic contacts or motors for software control via the Raspberry Pi GPIO or I2C. For automated systems, you would need a lens with electronic aperture control. This manual design is ideal for fixed-lighting setups or projects where you set the aperture once during installation.

Yes, the Arducam LN046 uses a standard C-Mount, making it compatible with any camera module or body that has a C-Mount interface. For mirrorless or DSLR cameras, you will need a C-Mount to your camera's mount adapter (e.g., C-Mount to Sony E-Mount). Ensure the camera's sensor size is compatible with the lens's 1-inch optical format to avoid severe vignetting. It is optically optimized for the Raspberry Pi HQ Camera's 12MP sensor size for full coverage.
