Description
Capture long-range details with unparalleled geometric accuracy using our 8MP 36mm M12 Ultra Low Distortion Lens. Specifically optimized for large-format 1/1.8″ and 1/2.3″ CMOS sensors, this professional-grade telephoto lens provides a highly concentrated field of view (11.7° horizontal on 1/1.8″). Featuring a reliable F2.4 aperture and an integrated optical filter (FILTER: Yes), it eliminates daylight color shifts while delivering crisp, 8-megapixel resolved imagery. Boasting a distortion rating of < 0.7%, it is the perfect ultra-compact solution for Intelligent Transportation Systems (ITS), narrow-angle machine vision, and long-distance CCTV surveillance.
Key Highlights

Applications & Compatibility
Core Application Scenarios
This 8MP 36mm M12 telephoto lens is engineered for long-distance tracking and high-precision target capture where minimal space is available for hardware integration. It is highly optimized for Intelligent Transportation Systems (ITS), including speed gun cameras, toll booth lane tracking, and Automatic Number Plate Recognition (ANPR) systems requiring crystal-clear lane isolation. The ultra-low distortion profile (< 0.7%) also makes it exceptional for Industrial Machine Vision lines where remote tracking is required, such as overhead crane orientation, deep logistics sorting tunnels, and high-altitude material profiling. Additionally, its compact profile allows it to fit easily into drone payloads for specialized UAV infrastructure inspection and high-end long-range CCTV perimeter fencing.

Frequently Asked Questions
- Q: What is the main advantage of a 36mm focal length on an M12 lens?
- A: A 36mm focal length acts as a narrow telephoto lens. It allows your camera system to remain at a safe or practical distance (minimum 1 meter) while physically magnifying small targets like license plates or barcodes with true 8MP resolution.
- Q: Does this telephoto lens require digital software-based distortion correction?
- A: No. With a geometric distortion rating below 0.7%, this low distortion lens preserves straight lines and precise proportions right out of the box, saving valuable processing power on your embedded controller.
- Q: Will this lens cause dark corners on a 1/1.8″ sensor?
- A: No, the lens is specifically optically engineered to accommodate a Max Φ10.3mm image circle. It fully covers 1/1.8″ and 1/2.3″ sensors with perfect edge-to-edge brightness and no vignetting.
- Q: What type of filter is integrated into this model?
- A: The “FILTER: Yes” specification means it comes with a built-in optical filter (typically an IR Cut Filter). This filter cuts off infrared glare during daylight hours to ensure precise color balance for AI analytics and traffic monitoring.
- Q: Can this lens handle heavy vibrations on industrial robotic arms or drones?
- A: Yes, the lens features a fixed focal and fixed iris mechanism, meaning it has fewer moving parts than a zoom lens. This rigid design makes it highly robust against mechanical shock and vibration drift.
- Q: Is the iris adjustable if lighting conditions change?
- A: No, this lens has a fixed F2.4 aperture. Provides stable, consistent light transmission — ideal for ITS strobe‑lit systems and factory controlled‑lighting environments.
