Sony ISX031 3MP Rolling Shutter CMOS Sensor for Vision

Answer: An M12 lens is a compact lens with a 12mm thread diameter, often called an S-mount lens. These lenses screws into a camera M12 lens mount and are easy to use. These lenses are 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​.

A: There are many embedded vision cameras and AI cameras that are compatible with M12 lenses. 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.

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