What is an M12 Fisheye Lens?
An M12 fisheye lens is a compact, wide-angle lens with a distinctive hemispherical design. It is named “M12” due to the 12mm threaded mounting system commonly used in machine vision, drones, and CCTV cameras. Unlike traditional lenses, fisheye lenses capture a much broader field of view—up to 180 degrees or more—allowing users to encompass entire scenes in a single frame.
The design typically includes multiple aspherical elements that minimize optical distortion and maintain sharpness across the frame. Shanghai Silk Optical Technology Co. Ltd produces high-precision M12 fisheye lenses optimized for low-light performance and edge-to-edge clarity, ensuring exceptional imaging quality for professional and consumer applications.

- Compact Size: Ideal for small cameras, drones, and embedded systems.
- High Optical Quality: Advanced coatings reduce glare and enhance color accuracy.
- Durable Build: Resistant to dust, moisture, and mechanical shocks.
- Versatile Mounting: Standard M12 threading simplifies installation.

Selection Guide: Choosing the Right Lens
When selecting an M12 fisheye lens, consider these key factors:
- Field of View: Choose based on the coverage area required. Wider angles suit surveillance, while narrower angles provide higher detail.
- Aperture: A larger aperture (f/2.0 or lower) is preferable for low-light environments.
- Compatibility: Verify the lens mount and sensor size match your camera system.
- Durability: For outdoor applications, select lenses with weatherproof and dustproof features.
- Optical Quality: Look for multi-coated, aspherical lens elements to reduce aberrations.
