Frequently Asked Questions

Is the Arducam LN041 lens compatible with the standard Raspberry Pi Camera Module V2?

No, the Arducam LN041 is designed specifically for the Raspberry Pi High Quality Camera (HQ Camera) due to its larger 1/2.3" sensor and CS-mount thread. The standard Camera Module V2 uses a smaller M12 mount and sensor, so this lens would not physically attach or cover the sensor correctly. For the HQ Camera, ensure you have the correct CS-mount adapter board or interface.

How do I adjust the focus on this manual lens?

To adjust focus, gently rotate the focus ring on the lens barrel while viewing a live feed from your Raspberry Pi HQ Camera. Use software like libcamera or Raspistill to preview the image. Turn the ring slowly until your subject appears sharp. For fixed-distance applications, you can set the focus once and secure the ring if necessary. Avoid using excessive force to prevent damage to the threading.

What is the benefit of the F/1.2 aperture on this lens?

The F/1.2 aperture is considered 'fast,' meaning it allows more light to reach the camera sensor. This results in better performance in low-light environments, enabling shorter exposure times and reducing motion blur. It also provides a shallower depth of field, which can help isolate a subject from its background for artistic or machine vision applications where background detail is distracting.
