Description
Capture an uncompromised, blind-spot-free perspective with our premium 6MP 2.2mm M12 Fisheye Lens. Specially engineered for large-format 1/1.8″ sensors with a Φ5.6mm image circle, this professional-grade fixed focal lens delivers a full 190° spherical field of view (FOV). Featuring an ultra-bright F1.8 large aperture and a rugged 6G all-glass structure, it provides exceptional 6-Megapixel low-light clarity and edge-to-edge resolution. This makes it the premier choice for developers seeking high-performance M12 lenses for machine vision, CCTV lens hardware networks, and automotive lens upgrades.
Key Product Highlights
- 190° True Circular Panorama: Delivers 190° diagonal, horizontal, and vertical coverage to replace multi-camera setups with a single wide-angle sensor.
- F1.8 Ultra-Large Aperture: Maximizes photon capture to provide crystal-clear image data in low-light environments, significantly outperforming standard F2.0 or F2.2 options.
- 6-Megapixel Resolving Power: Built with 6 layers of precision-ground glass to yield sharp 6MP resolution, completely eliminating pixelation on modern HD sensors.
- Compact 26.99mm TTL Design: The short 26.99mm Total Track Length enables seamless mechanical integration into compact housings without adding system weight.

Target Applications & Compatible Devices
Core Application Scenes
This ultra-bright 6MP fisheye lens is meticulously designed for high-end automotive surround-view systems (360° cameras) and advanced fleet monitoring dashboards where low-light vision and full spatial awareness are safety-critical. Its robust 6G optical profile thrives under harsh environmental conditions, making it an excellent match for ceiling-mounted panoramic dome cameras in large warehouses, bank lobbies, and public transit terminals. Furthermore, with an ultra-close minimum object distance of 0.1 meters, it acts as an efficient imaging tool for machine vision industrial robots, automated guided vehicles (AGVs), and smart retail checkout scanners.

Frequently Asked Questions
Q: Can this lens be utilized on standard 1/2.8″ or 1/3″ sensors?
A: Yes, it is mechanically compatible with M12 mounts. However, because it is optimized for a larger 1/1.8″ sensor, using it on smaller 1/2.8″ or 1/3″ sensors will crop the peripheral edges, resulting in an FOV smaller than the rated 190°.
Q: What is the main benefit of the F1.8 aperture over standard F2.2 lenses?
A: An F1.8 aperture allows significantly more light to reach the camera sensor. This drastically improves nighttime performance, reduces image noise, and allows for shorter shutter speeds to prevent motion blur in automotive or industrial lines.
Q: How does the -94% optical distortion affect the image output?
A: This negative value represents the barrel distortion required to condense a massive 190° environment onto a flat sensor plane. It creates a classic circular fisheye lens effect, which can easily be flattened or de-warped in real-time using camera software or standard VMS platforms.
Q: Does a 6G structure mean there are plastic elements inside?
A: No. The 6G moniker signifies a 100% all-glass design consisting of 6 precision glass layers. Glass optics provide superior thermal stability compared to plastic, preventing the lens from drifting out of focus when exposed to extreme engine heat or freezing weather (-40°C to +85°C).
Q: Is the focus mechanism adjustable or pre-fixed?
A: The lens features a fixed focal design with standard M12x0.5 threading. You manually adjust the focus during system assembly by threading the lens into your camera holder until the image is sharp, then lock it securely using a standard M12 lock ring or set screw.
