In order to meet the increasing market demands for more lens options to address different use cases, Arducam selected and tested a wide range of M12 mount optimal lenses from long focus to fisheye for shooting on your Raspberry Pi or Arduino cameras. It’s now much easier for you to get the best lens you’ll need, and we will keep the lens list growing in the near future.
1.Choose a suitable lens holder as follows:
a) Determine the lens holder height listed in the lens specifications for your selected lens. If you use a different lens holder height, you might not be able to focus the lens at all.
b) Ensure that the lens holder matches the screw hole pitch of your camera board. Lens holders are available with18mm and 20mm pitches.
2.If required, the thread gap between the lens and lens holder can be filled with damping grease or similar glue in order to fix the lens in position after focusing.
3.Specks of dust or tiny bubblers might be visible on the image while focusing the lens. These will disappear when the lens is in focus, and will not affect image quality.
4.When focusing or replacing a lens, do not screw the lens into the lens holder too deep, otherwise the lens might touch and damage the image sensor. Often, focusing a lens is performed while monitoring the image quality on a video screen. A blurry image will result if the lens is screwed in either too deep or too shallow from where it is in focus.
5.You have to manually remove the IR filter at the bottom of the lenses when using them with a NoIR camera

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 – we selected, tested and labeled a bunch of lenses and shrinks it all into a complete toolbox on your palm
What’s in it: This kit includes 10 M12 Lenses to cover almost any angles of view you’ll ever need, 10°/20°/40°/60°/80°/100°/120°/140°/160°/200° respectively on a 1/4” Pi Camera like OV5647 and IMX219. M12 lens holders, screws, specifications and even cleaning cloth are also in the box
What else is needed: It makes a perfect combo with “Arducam B0031”, 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 kit 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. Replace it with the next if it is not the best. Video: youtu.be/23jE0l8PTKA
NOTE: The 4 lens holders included come with 18mm/20mm hole spacing and 7mm/13mm heights. Typically lenses with a larger Field of View will require shorter holders, and that means you need to change the lens holder if the lens does not focus at all. Arducam CS Mount Cameras also work with this kit with holders replaced
