As a professional camera seller and manufacturer, Arducam wants to make it as easy as possible for our customer to get what they want. After the release of many M12 lenses, it's time to introduce a group of M12 mount holders that are needed. This time, Arducam selects and tests a range of M12 mount lens holders in metal and plastic with 18mm and 20mm hole spacing, and provides datasheets and mechanical drawing that you might need in your project. M12 mount lens holders are finally becoming organized.
