Description
1/2.7″ 2.9mm M12 Ultra-Wide Angle Lens
Empower your vision hardware with this industrial-grade 1/2.7″ 2MP 2.9mm M12 ultra-wide angle lens. Meticulously optimized for mainstream 1080P sensors like the OV2710, this high-performance lens delivers an expansive 164° diagonal field of view in full 2-megapixel clarity. Featuring a robust 5G+IR cut (5 All-Glass Elements + Infrared Cut Filter) optical formulation and a bright F2.2 aperture, it provides exceptional image definition and pristine color accuracy. With its compact footprint and TV distortion controlled under 26%, it serves as an excellent optical solution for wide-area surveillance, automotive dashcams, and smart home IoT terminals.
Key Product Highlights
- 164° Panoramic Wide-Angle Coverage: Provides sweeping, ultra-wide perspectives (130°H / 66°V) to seamlessly eliminate visual blind spots across your entire scene.
- Optimized 2MP Full HD Clarity: Precision-engineered to match 1080P resolution sensors, guaranteeing edge-to-edge contrast and sharp detail mapping for analytics.
- Premium 5G All-Glass Structure: Built entirely with 5 premium layers of optical glass to ensure exceptional light throughput and total immunity to thermal focal shift.
- Low TV Distortion (<26%): Uniquely controlled for a 164-degree wide lens, suppressing barrel distortion to keep horizons natural compared to typical fisheyes.
- Standard M12 Threaded Mount: Features a classic M12x0.5 interface with a short 5.21mm Back Focal Length, enabling ultra-low profile integration into tight camera housings.

Applications & Device Compatibility
Core Application Scenarios
This 2MP M12 wide angle lens is intentionally engineered for environments that require full panoramic awareness within compact hardware footprints. It acts as an ideal optical component for automotive front-facing dashcams, rear-view backup cameras, and 360-degree surround-view rigs where weather resistance and structural durability are required. In commercial environments, it excels in smart retail video doorbells, ATM security kiosks, and smart apartment unit door intercoms, allowing users to capture full room widths or a visitor’s entire upper body at close range. Additionally, its lightweight design makes it a top tier candidate for FPV drone navigation, robot situational awareness, and smart parking enforcement networks.

Frequently Asked Questions
- Q: Why is this lens specifically optimized for the OV2710 sensor?
- A: The lens is designed to perfectly illuminate the active pixel area of 1/2.7″ formats like the OV2710 sensor, ensuring the exact 164° diagonal field of view is reached without creating dark corners or vignetting.
- Q: What is the significance of “TV Distortion <26%” on a 164° lens?
- A: For an ultra-wide angle lens, keeping TV distortion under 26% is an exceptional optical achievement. It means the image retains an immersive wide-area layout while significantly reducing the extreme edge curving common in standard fish-eye optics.
- Q: Will this lens de-focus when the camera gets hot?
- A: No. Thanks to the 5G (5 All-Glass) optical construction, this lens provides superb thermal stability. Unlike cheap plastic lenses that warp and cause blurred images under hot sun or running chips, glass lenses maintain an invariant focal plane.
- Q: Does this lens support night-vision recording?
- A: Yes. The F2.2 aperture delivers stable light transmission. When your camera module switches to night mode or triggers external infrared LEDs, the built-in glass elements accurately process the light spectrum for sharp imaging.
- Q: How is the manual focus configured on this lens?
- A: During hardware assembly, the operator manually screws the M12 lens into the thread base while monitoring a live video feed. Once the target distance achieves peak sharpness, the lens is permanently locked with a fixing nut or optical adhesive.
