What are M12 lenses/S-mount lenses ?

M12 lenses, also known as s-mount lenses are compact size lenses useful for a variety of embedded cameras. The barrel of these lenses are machined with M12 threads allowing easy mounting and focusing with M12 lens holder. M12 lenses are sometimes called board-mount lenses. Please note that other lens mount options are also possible in addition to M12 lens mount. This article compares commonly seen lens mount options.

How to choose a M12 lens/S-mount lens ?

Sunex pioneered the development of M12 lenses/s-mount lenses. We design and manufacture M12(s-mount) lenses in our own facilities with proven high-quality processes (automotive). We provide a suite of optical calculators (aka optics wizards) for selecting the right M12 lens for your application. Read a step-by-step guide for choosing the right M12 lens/s-mount lens.
