Q: What is an M12 lens (S-mount lens)?

Answer: An M12 lens is a compact lens with a 12 mm thread diameter, often called an S-mount lens. These lenses screws into a camera’s M12 lens mount and are commonly used in board-level cameras for embedded vision systems. M12 lenses are smaller than C/CS-mount lenses, making them ideal for space-constrained applications like robotics​.

Q: What cameras can I use M12 lenses with?

A: There are many embedded vision cameras and AI cameras that are compatible with M12 leness. As long as camera's lens holder is compatible with the mechanical dimensions of the lens, the lens should focus! Please make sure to match the image circle, FoV, and resolution.

Q: How do you focus an M12 lens?

Answer: Use focus targets, then slowly thread the lens while displaying a video. Go past focus, then come back to focus. You can view our full article on how to focus camera lenses.
