Description
1/2.7″ 3.7mm F2.0 M12 Wide Angle Lens
Upgrade your optical systems with this professional 1/2.7″ 2MP 3.7mm M12 wide-angle lens. Meticulously optimized for mainstream 1080P image sensors such as the OV2710, this high-performance lens delivers a broad 120° diagonal field of view with crystal-clear 2-megapixel resolution. Featuring a premium 6G+IR cut (6 All-Glass Elements + Infrared Cut Filter) optical design and a bright F2.0 aperture, it provides exceptional image definition, high light throughput, and outstanding color fidelity. With an ultra-low geometric distortion of -28% for its wide profile, it is an excellent choice for advanced security surveillance, automotive vision, and intelligent IoT terminals.
Key Product Highlights
- 120° Wide-Angle Perspective: Captures an expansive field of view (97°H / 52°V) to eliminate visual blind spots while maximizing coverage across your scene.
- Low Optical Distortion (-28%): Exceptionally well-corrected for a 120-degree wide lens, suppressing barrel curving to keep edges linear and natural for algorithmic analytics.
- Premium 6G All-Glass Structure: Built entirely with 6 precision layers of optical glass, ensuring maximum light transmission and complete resistance to heat-induced focus drift.
- Bright F2.0 Large Aperture: The large fixed F2.0 iris allows massive light intake, delivering bright, low-noise imagery and excellent clarity even in dim indoor or low-light conditions.
- Full HD 2MP Resolution Optimization: Precision-calibrated to match 1080P pixel densities, guaranteeing edge-to-edge contrast and sharp detail mapping for facial and object recognition.

Applications & Device Compatibility
Core Application Scenarios
This 2MP M12 wide angle lens is intentionally engineered for modern visual applications that require an expansive spatial layout combined with strict geometric accuracy. It serves as an ideal optical module for AI facial recognition gates, smart video doorbells, and office attendance systems, where capturing a complete torso profile without heavy wide-angle distortion is highly valued. Thanks to its rugged 6G all-glass structure, it excels in automotive front-facing dashcams, fleet telematics camera boxes, and backup cameras that are exposed to extreme sunlight and temperature fluctuations. Additionally, it offers stable performance in commercial ATM security kiosks, medical inspection pods, and embedded machine vision sorting setups.

Frequently Asked Questions
- Q: What are the main benefits of the 6G all-glass construction?
- A: All-glass optics maximize light transmission, provide scratch resistance, and completely prevent “thermal drift” (de-focusing) when the camera module generates operational heat or is exposed to hot summer sun.
- Q: How does the -28% distortion rating help my vision system?
- A: For an ultra-wide lens of 120°, a distortion of -28% is exceptionally low. This means the lines in your video remain straight and proportions stay natural, which vastly improves facial recognition accuracy and minimizes the need for software-based digital dewarping.
- Q: Can this lens be utilized on smaller sensor sizes?
- A: Yes, it can be mounted on 1/3″ or 1/4″ sensor arrays. While it is fully compatible, please note that the field of view will crop proportionally, yielding a slightly narrower viewing angle than 120° while maintaining absolute central sharpness.
- Q: Does this lens include a built-in filter for daytime color precision?
- A: Yes, it features an integrated IR cut filter (IRCF) that blocks unwanted infrared wavelengths during daytime shooting, preventing color washing and ensuring vibrant, true-to-life images.
- Q: How is the manual focus configured on this fixed focal M12 lens?
- A: Focus is set manually during your camera module’s assembly phase. The operator screws the lens into the M12 thread block while viewing a live screen output. Once crisp focus at your target distance is established, it is locked using a locking ring or a drop of optical adhesive.
