Find an M12 Lens / S-Mount Lens
M12 Lenses are miniature lenses for embedded cameras, computer vision, and human viewing camera applications.
Despite their small size, M12 lenses deliver high-quality imaging and are a cost-effective alternative to larger C-mount lenses. Engineers favor these lenses for projects where space is limited or weight should be minimal, without sacrificing image performance.
We offer many types of M12 lenses including fisheye, wide-angle, no-distortion, and telephoto types. These lenses support various image sensor sizes and resolution, making them practical for a wide range of applications.
We have >200 lenses with accurate specifications, downloadable .STP files, and same-day global sample shipping. All of our lenses are ready for mass production.
Ask us about customizations, custom lens designs, and camera module assembly.
Our low F#, low distortion, and/or ingress protected lenses are ideal for automotive, mobile robotics, and aerial robotics.
Our 16mm, 25mm, and 50mm M12 lenses are great for long-distance imaging, and tiny fisheye lenses ideal for obstacle avoidance.
Our miniature fisheye, telephoto, and IR Corrected lenses are suitable for doorbell cameras and active IR illuminated scenes.
Our lenses are available with multiple F# and customizations allow you to quickly optimize any camera design.

There are many M12 Lens Types and Options
Board mount lenses are available in a range of options to enable you to create a vision system that is customized to your use-case.
Many of our M12 lenses are available in multiple apertures (F#) and with special features like ultra low distortion or ingress protection for harsh environments. They support various image sensor sizes (from small 1/4” sensors up to 1/1.8” or larger) and resolutions (including multi-megapixel HD and 4K sensors), making them practical for a wide range of cameras.
A few types of lenses are:
- Fisheye Lenses: Ultra-wide field of view (up to ~180°+) for maximum coverage, ideal for panoramic imaging and obstacle avoidance.
- Wide-angle lenses: Large field of view with low distortion, great for surveillance and machine vision applications.
- No-distortion / Low-Distortion Lenses: Engineered optics that minimize distortion for accurate image reproduction without dewarping or calibration.
- Telephoto Lenses: Longer focal lengths (e.g. 16 mm, 25 mm, 50 mm) for narrow FOV imaging, useful in drone imaging at altitude or long-range security cameras.
- IR-Corrected Lenses: Optimized for both visible and infrared light (day/night use), suitable for security cameras with IR illumination (e.g. doorbell cameras or CCTV).
Choosing the Right S-Mount Lens
When choosing an S-Mount lens (M12 lens), there are several factors to consider. Common considerations include:
- Field of View: A shorter focal length is ideal for wide-angle applications, while a longer focal length is better suited for telephoto applications.
- Depth of Field: the depth of field of a lens determines the range over which objects are in focus.
- CMOS Sensor Format: the format of your sensor will determine which lenses will provide full coverage, or the crop ratio for FoV.
- Resolution: The lens MTF or sharpness needs to match the sensor's pixel pitch (size) otherwise you'll have a blurry image.
- F#: The amount of light that the lens collects is dependent on the aperture diameter.
- Ingress Protection: If your application is outdoors, having an ingress protected lens eliminates the need for a window or dome.
- Chief Ray Angle: The CRA of a lens needs to match your image sensor within ~+/-5~7 degrees otherwise color shading may be an issue.
- Operating Temperature: the range in which a camera stays in focus is partially dependent on the lens construction (glass versus glass+plastic)
By considering these factors, you can choose the right S-mount lens for your application, regardless if it's high resolution or low resolution.
