  • Low Distortion M12 Mount lens mainly   for Arduino and Raspberry Pi cameras, please contact us for other platform.
  • Why we need it: In case you’re disappointed with the fixed official cameras and want precise control of what gets into the frame of your image – like how wide and how close it is
  • What else is needed: It makes a perfect combo with “Arducam B0031 or B0103”, a more flexible and slightly larger camera module for Raspberry Pi that uses M12 lenses to frame up the best image. You can’t use this lens directly with the official Raspberry Pi Camera Module V2 because an M12 holder or 18/20mm hole spacing of the camera board is required
  • How to use it: Get a camera with an M12 lens holder, and screw one lens slowly into the M12 lens holder until you see a clear and sharp image on a video screen. Screw it out a little if you want to shoot objects close to the camera.
