Arducam LN051 CS Lens for Raspberry Pi HQ Camera, 3.2mm 120° UltraWide

No, the Arducam LN051 is specifically designed for the Raspberry Pi High Quality (HQ) Camera, which uses a larger IMX477 sensor and a CS-mount interface. The standard Camera Module V2 uses a smaller M12 mount and a different sensor size, so this lens will not mount or focus correctly on that module. For the HQ Camera, ensure you have the correct CS-mount adapter board installed.

To adjust focus, gently rotate the focus ring on the lens barrel while your Raspberry Pi HQ Camera is streaming a live preview. Use software like libcamera-hello or a Python script with Picamera2 to view the image output. Rotate the ring slowly until your subject appears sharp. For best results, perform this adjustment under the typical lighting and distance conditions of your final application, as focus can shift slightly with aperture and distance changes.

On the Raspberry Pi HQ Camera with its 12.3MP IMX477 sensor, the Arducam LN051 provides an approximately 120-degree horizontal field of view. The vertical and diagonal fields of view will be smaller. This ultra-wide perspective is significantly broader than the standard lens, making it ideal for applications like room monitoring, panoramic photography, or robotic navigation where capturing a large area is more important than fine detail at a distance.

While designed and tested for the Raspberry Pi HQ Camera, the LN051 is a standard CS-mount lens with a 1/1.7" optical format. It can physically attach to any camera system with a CS-mount interface, provided the sensor size is compatible (up to 1/1.7"). However, the stated 120-degree field of view is calibrated for the IMX477 sensor's specific dimensions. On a different sensor, the effective field of view and possible vignetting will vary, so testing is recommended for non-Raspberry Pi applications.
