Description
Eliminate optical blind spots completely with this high-performance 4MP 1.0mm M12 fisheye lens. Optimized for high-resolution 1/3.2″ format sensors (including the OmniVision OV4689), this premium miniature lens captures an incredible 205° panoramic field of view (D/H/V) across a single sensor frame. Featuring a bright F2.2 aperture and an ultra-short 12.00mm T.T.L., it delivers crisp 4-megapixel clarity from the center to the ultra-wide edges. Built with a robust 6G all-glass structure and an integrated IR cut filter, this fixed focal lens is the premier choice for compact drone navigation, smart e-commerce security pods, and advanced automotive surround-view systems where space is at a premium.
Product Highlights
- 205° Full Panoramic Coverage: Provides a true 205-degree hemispherical field of view horizontally, vertically, and diagonally, replacing multi-camera setups with a single, cost-effective lens module.
- 4 Megapixel HD Sharpness: Engineered explicitly for 4MP CMOS sensors to resolve fine details and clear shapes, mitigating pixel loss at the periphery of the image circle.
- Ultra-Shallow 12.00mm T.T.L. Profile: Features an exceptionally compact 12.00mm Total Track Length and a 1.23mm mechanical B.F.L., fitting seamlessly into ultra-thin smart home hardware and micro drone frames.
- 6G All-Glass Thermal Stability: Built with 6 high-precision glass elements that prevent focal shift or image degrading under extreme outdoor temperatures, outperforming cheap plastic alternatives.

Applications & Target Devices
This 4MP M12 wide angle lens is purposefully crafted for compact spatial environments where maximizing the visible perimeter is vital. Its exact Φ2.9mm image circle fits standard 1/3.2-inch imaging arrays perfectly, producing an ultra-wide panoramic projection ready for edge-algorithm de-warping. The fast F2.2 aperture and multi-coated 6G all-glass structure ensure excellent contrast and brightness, even during low-light night-time tracking or fast-exposure automated routines. Equipped with an integrated IR cut filter, it cuts out near-infrared distortion during daylight hours, preventing pink hue artifacts and delivering professional color accuracy across continuous security deployments.
Compatible Device List:
- Automotive Safety Systems: Designed for vehicle 360-degree around-view monitors (AVM), blind-spot detection (BSD) cameras, and truck fleet cabin security recorders.
- Drone & UAV Lenses: Ideal as a lightweight navigation payload, automated obstacle avoidance camera, or agricultural drone terrain scanner.
- Smart Home Security: Perfectly fits high-definition video doorbells, residential peepholes, and Tuya/Mi Home smart IoT panoramic mini-dome cameras.
- CCTV & Industrial Imaging: Fits 1/3.2″ 4MP sensors (such as OmniVision OV4689) used in 360° ceiling warehouse cameras, ATM terminals, and micro-robotic arm safety perimeters.
Designed for 360-degree panoramic surveillance, UAV aerial navigation, and automotive surround-view applications.
Frequently Asked Questions
Q: Why does the technical sheet state an optical distortion of <-117%?
A: In optical manufacturing, a negative distortion rate over 100% is the standard geometric metric for a circular fisheye lens. It denotes that the lens actively compresses an expansive hemispherical perspective (205°) into a flat circular image on the sensor, creating the traditional fish-eye effect.
Q: Can this lens cover a full 1/3″ or 1/2.8″ sensor grid?
A: This lens is optically optimized for the 1/3.2″ image format (Φ2.9mm image circle). While it will mechanically screw into an M12 thread over a 1/3″ or 1/2.8″ sensor, it will result in severe black borders (vignetting) around the outer perimeter of your screen.
Q: What is the operational benefit of the 6G all-glass structure over plastic lenses?
A: Plastic lenses swell and warp when exposed to solar heat, causing the focus to drift and blur. Our 6 Glass (6G) elements provide pristine light transmittance and zero thermal drift, making this industrial lens remarkably reliable in harsh outdoor or engine-bay climates.
Q: Is the iris or focus adjustable on this camera module?
A: This is a Fixed Focal Lens configured with a Fixed Iris (F2.2). The focus itself is adjustable during hardware installation by threading the lens into your M12x0.5 base until the sensor reads maximum clarity, after which it is secured with an adhesive or lock ring.
Q: How does the 0.1m M.O.D. help with micro security configurations?
A: The Minimum Object Distance (M.O.D.) of 0.1 meters (10cm) ensures that any subject tracking within 10cm of the front glass element stays in crisp, sharp focus. This is highly useful for smart video doorbells where visitors move exceptionally close to the portal lens.
Q: Do you offer bulk customization for low-light or daytime/nighttime dual-band setups?
A: Yes, we provide extensive OEM/ODM production modifications. We can remove the IR cut filter entirely to enable true infrared night vision, or supply dual-band filters (650nm + 850nm/940nm) tailored to your manufacturing parameters.
