Description
2.8mm M12 Wide Angle Lens | 140° F.O.V. Industrial CCTV Lens
Upgrade your optical systems with our premium 2.8mm M12 Wide Angle Lens. This ultra-compact Fixed Focal Lens is engineered with a high-definition 2MP (1920×1080) resolution and a fast F2.0 aperture, delivering exceptional clarity even in challenging lighting conditions. Tailored for 1/2.7″ sensors, it breaks the limits of narrow viewing zones by offering an expansive 140° diagonal field of view. Whether you are upgrading CCTV Lens modules, deploying an Industrial Lens for automation, or designing compact Automotive Lens systems, this optics solution eliminates blind spots and captures every critical detail.
Key Highlights
- Ultra-Wide 140° Panoramic View: The 2.8mm focal length expands your field of view to 140°(D) / 118°(H), significantly reducing blind spots in monitoring zones without requiring panning hardware.
- Full HD 2MP Sharpness & F2.0 Aperture: Optimized for 1080P resolution with a bright F2.0 iris, ensuring crisp image definition and low-noise video capture even in low-light environments.
- Industrial-Grade 2G4P Construction: Built with an advanced 2G4P (2 Glass + 4 Plastic) optical structure to minimize thermal drift, maintaining sharp manual focus across fluctuating temperatures.
- Standard M12 Threaded Mount: Features a universal M12x0.5 interface, ensuring seamless mechanical compatibility and rapid drop-in integration with mainstream sensor boards.

Target Applications & Compatible Devices
This mini M12 Wide Angle Lens is purpose-built for high-density, compact environments where maximizing the field of view is paramount. It excels in smart home ecosystem accessories like video doorbells, residential access control systems, small-footprint dome cameras, automotive rear-view/dash cams, and robotic automated guided vehicles (AGVs). Its ultra-compact T.T.L. allows it to fit snugly into weather-resistant housings without requiring any bulky chassis or custom lens bracket modifications.
The lens is highly compatible with industry-standard 1/2.7″, 1/2.8″, and 1/3″ CMOS sensors (such as the Omnivision OV2710). It integrates seamlessly with mainstream security surveillance modules, smart IoT camera kits, and industrial machine vision hardware. Custom tuning for specialized FOV or focal lengths is available upon request to meet unique OEM project demands.
“Designed for Wide-Angle Security and Smart IoT Device applications.”
Frequently Asked Questions
Q: Will this M12 wide-angle lens cause fish-eye image bending?
A: This lens features a 140° diagonal field of view with a controlled optical distortion of <-59%. While it provides an ultra-wide perspective, the distortion balance is optimized for wide-area monitoring, making it perfect for human recognition and security tracking.
Q: Can I use this lens on a sensor smaller than 1/2.7″?
A: Yes, it is backward-compatible with smaller sensors like 1/2.8″ and 1/3″. However, please note that using a smaller sensor will slightly crop the image and narrow the effective field of view (FOV).
Q: Is the focus adjustable on this lens?
A: Yes. While the focal length and zoom are completely fixed, the focus mechanism is manual. You can easily calibrate and lock the sharpness by screwing the lens into your M12 mount board until the image is clear.
Q: Does this lens include an IR-cut filter for night vision?
A: This specific module is a standard optical lens. For complete day/night infrared functionality, it is recommended to pair it with an external electronic IR-cut switcher mounted on your sensor board.
Q: What does the 2G4P construction mean for product quality?
A: 2G4P means the optical assembly consists of 2 Glass elements and 4 Plastic elements. The glass layers protect against heat distortion and aging, ensuring the lens maintains stable image quality over years of outdoor operation.
