Arducam LN037 CS-Mount Wide Angle Lens for Raspberry Pi HQ Camera, 6mm F1.2

No, the LN037 is designed specifically for the Raspberry Pi High Quality Camera, which uses a CS-mount interface. The standard Camera Module V2 uses a smaller M12 mount and is not physically compatible without an adapter. The lens provides a 65° horizontal field of view on the HQ camera but a narrower 37° field on older V1/V2 modules if mounted via an adapter.

The lens features manual control rings. Rotate the front ring to adjust the manual focus, moving the lens element to sharpen your subject. The aperture is adjusted by rotating a separate ring near the camera mount, which opens or closes the iris blades from F1.2 to a smaller aperture. For best results, preview the image on your Raspberry Pi display while making adjustments in well-lit conditions.

The fast F1.2 aperture allows significantly more light to reach the camera sensor compared to standard lenses. This is crucial for Raspberry Pi projects operating in low-light environments, such as indoor surveillance or night-time photography, as it enables faster shutter speeds, reduces image noise, and improves overall image clarity without requiring additional external lighting.

Yes, the LN037 is well-suited for machine vision. Its wide 65° field of view is excellent for capturing larger scenes or multiple objects. The manual focus allows you to set a fixed focal plane for consistent imaging, and the sharp optics help in reading text or identifying details. The adjustable aperture also lets you control the depth of field to keep your target in focus.
