Description
1/2.5″ 2.4mm 5MP F2.0 M12 Ultra-Wide 218° Fisheye Lens
Unlock ultimate full-panoramic awareness with our professional 1/2.5″ 5MP 2.4mm M12 ultra-wide angle fisheye lens. Meticulously optimized for high-density 5-megapixel (2K Ultra HD) image sensors like the MT9P031, this premium lens captures an incredible 218° diagonal field of view to achieve comprehensive edge-to-edge surveillance. Featuring a bright F2.0 large aperture and an advanced 7G+IRCF (7 All-Glass Elements + Infrared Cut Filter) optical structure, it maximizes light gathering to capture pristine, sharp contrast while remaining completely immune to heat-induced focus drift. It stands as the premier optical solution for panoramic surveillance, automotive intelligent vision, and autonomous AI hardware requiring zero blind spots.
Key Product Highlights
- 218° Super-Panoramic Blind-Spot Elimination: Delivers an ultra-wide panoramic perspective (148°H / 108°V) to seamlessly capture a full hemispherical overview with a single camera module.
- 5MP High-Definition Resolving Power: Precision-calibrated optics perfectly resolve fine textures on 5-megapixel sensor matrices, ensuring crisp, edge-to-edge text and detail identification.

Applications & Device Compatibility
Core Application Scenarios
This 218° super fisheye lens is intentionally engineered for specialized vision hardware applications requiring complete full-view orientation and high 5MP pixel data density. It serves as a core optical component for commercial 360-degree ceiling dome cameras, smart parking enforcement networks, and virtual reality (VR) multi-lens stitching rigs. Thanks to its rugged 7G all-glass structure, it excels within automotive surround-view monitoring systems (AVM), heavy machinery blind-spot systems, and smart fleet dashcams. Furthermore, its hemispherical visual angle makes it a top-tier candidate for autonomous AGV robotics obstacle avoidance, drone navigation, and premium smart home panoramic intercom pillars.

Frequently Asked Questions
- Q: Why is the field of view listed as 218°? Is that a fish-eye visual effect?A: Yes, absolutely. A field of view of 218° goes beyond a standard flat horizon, allowing the camera module to actually see slightly “behind” its own mounting plane. This creates an immersive, hemispherical fisheye effect that captures an entire room or intersection with no blind spots.
- Q: How does the <-99% distortion value affect my vision system data?A: This ultra-high distortion is a natural optical characteristic of extreme 218° fisheye lenses, allowing them to map a huge dome-like environment onto a flat sensor. In practical use, this barrel-shaped image is typically flattened and corrected in real-time using backend software dewarping algorithms.
- Q: What are the main benefits of the 7G all-glass structure over plastic alternatives?A: Plastic lenses are prone to warping under high heat, causing the video stream to go out of focus (thermal defocusing). The 7G all-glass architecture guarantees maximum scratch resistance, superior light transmission, and complete focal plane stability from hot sun exposure to freezing winters.
- Q: Does this lens include a filter for daytime color precision?A: Yes, it features an integrated IR cut filter (IRCF) that accurately filters out ambient infrared wavelengths during daytime operations, preventing color washing and ensuring vibrant, true-to-life images with zero pink tinting.
- 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 analyzing a live reference monitor. Once crisp focus at your target distance is established, it is permanently locked using a locking nut, thread ring, or optical adhesive.
