Select A 4K+ M12 Lens (S-Mount) For Your Camera

M12 Lenses / S-Mount Lenses

An M12 lens is a board camera lens with 12mm diameter threads. These are commonly used in computer vision, surveillance, robotics, and machine vision. Our lenses range from 1mm to 25mm EFL and include fisheye, wide-angle, and no-distortion lenses. 

These lenses are also referred to as S-Mount Lenses or Board Mount Lenses, and are compatible with board cameras from FLIR, Econ-systems, iDS, Basler, The Imaging Source, and more. 

M12 Lenses can can outperform many C mount lenses and DSLR lenses because they do not have mechanical flange focal distance constraints.

These lenses can be used with many CS and C Mount cameras like the Raspberry Pi High Quality if an adapter is used. Read our M12, CS, and C Mount compatibility article if you have a CS or C mount camera or want to understand the difference between M12/S-mount and C-mount lenses.
