What is M12 Mount and M12 Lens
M12 means that the diameter of the lens thread is 12mm, and it’s also known as the S-Mount lens because it is S (Smaller, Shorter) compared to the C/CS mount lenses.
M12 lens is a series of lenses to be installed in the M12 mount lens base, usually used for applications where compact size is required. The M12 lens was initially widely used on CCTV cameras for surveillance, but it also prevails among the embedded cameras as a qualified alternative to the C/CS Mount lens.
Why M12 lenses on Raspberry Pi and other embedded systems
The M12 lenses are perfect for the board-level cameras, and it’s cost-effective for lower-end products. The Raspberry Pi camera, on the other hand, comes with nearly no support of interchangeable lenses before the Raspberry Pi High Quality Camera is out. Customers are stuck with the stock lens, which is around 60 degrees horizontal if they are not informed of the third-party modules. Even after the High Quality Camera with C/CS-Mount is out, the M12 Lenses are still needed because it helps to cover the needs of a wider field of view or fisheye cameras.
Use an M12 Lens on a CS-Mount
Because the M12 lens is a threaded lens, it can be mounted with a proper thread. Therefore, we can adapt it from other mounts, such as the CS-Mount. Since the release of the 12MP IMX477 Raspberry Pi High Quality Camera, there is an increasing need of adapting CS-Mount to fit an M12 lens. You can read the blog below to know more about how this process works.

What M12 lenses does Arducam offer
The majority of Arducam M12 lenses are selected for and tested on 1/4″ (Arduino camera, Raspberry Pi Camera V1&V2) and 1/2.3″ image sensors (Raspberry Pi High Quality Camera like IMX477 Modules), but it can also be used on other image sensors as long as the lens optical format is compatible.
We offer M12 lenses of different focal length and optical distortion. The focal lengths of our M12 lenses range from 1mm (fisheye end) to 25mm(telephoto end). Arducam also offers M12 lenses with little optical distortion for applications where an accurate digital restoration of the object is required.
To better meet the needs, we’ve packed lenses with different focal lengths into a lens kit, and lenses with optical distortion into another. You can also refer to Lens Products from Arducam for more information.
