Arducam M12 Lens Set, Arducam Lens for USB Camera(1/2.7” 1/2.8″ 1/2.9″), Telephoto, Macro, Wide Angle, Fisheye Lens Kit (20°- 180°) with M12 Lens Holder and Cleaning Cloth, Optical All-in-One

Why we need it: In case you’re disappointed with the angle of default 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, 20°/25°/40°/55°/70°/80°/90°/125°/150°/180° respectively on a 1/2.8” USB Camera like B0200 IMX291 camera. M12 lens holders, screws, specifications and even cleaning cloth are also in the box

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 hole spacing and 20mm hole spacing. 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.
