Review on Arducam for Raspberry Pi Camera: Interchangeable CS Mount Lens for Pi 4, 3, 3B+ | 5MP OV5647 1080P by Pedro Movie

Good quality at a good price and delivered on time via Prime I've been looking for ways to connect the Raspberry Pi camera to telescopes and microscopes and the C/CS mount thread seemed like a good option to me to be. The mount on this board is metal, and the included lens worked for me right out of the box. The lens has a focus ring with locking screw. I will try many other lenses in different applications. So far I have tested the mechanical parts and they work well. Arducam also offers a 12mm x 0.5mm CCTV or MTV mount version of this board which I have had for a while. If you're looking for a lighter board but with interchangeable lenses, this is your best option. I now have both for different uses. I have not been able to find adapters for 12mm threads on a standard 1.25" telescope or 23mm microscope eyepiece where the c/cs mount is prevalent. It would be nice to see an 8 megapixel version of the board at some point.
