Description
Maximize your narrow-angle observation and long-distance inspection accuracy with our 2MP 35mm M12 Low Distortion Lens. Expertly engineered for standard 1/2″ CMOS sensors, this professional telephoto lens offers a highly focused 10.5° horizontal field of view to isolate targets from a distance. Featuring an integrated optical filter (FILTER: Yes) for reliable color rendition and a < 0.8% ultra-low distortion profile, it delivers exceptionally crisp 2-megapixel resolution. It is the perfect compact solution for specialized machine vision positioning, precision factory automation, and long-range CCTV monitoring applications.
Key Highlights
- 35mm Telephoto Narrow Field: Yields a concentrated 10.5° horizontal FOV, allowing you to capture far-away objects or zoom in mechanically on specific inspection zones without physical relocation.
- Ultra-Low Geometric Distortion (< 0.8%): Ensures highly accurate linear reproduction, completely eliminating barrel or pincushion bending for demanding alignment and reading tasks.
- Industrial-Grade 300mm M.O.D.: Features a short Minimum Object Distance of 300mm (0.3m) for a long focal lens, making macro-telephoto close-up setups possible in tight machinery spaces.
- Integrated Optical Filter Stability: Built-in filter configuration blocks stray light artifacts to maintain precise color fidelity and image contrast under variable production-floor lighting.

Applications & Compatibility
Core Application Scenarios
This 2MP 35mm M12 telephoto lens is uniquely optimized for environments requiring localized tracking, narrow-channel monitoring, and distant optical inspection without edge stretching. It excels in Industrial Machine Vision systems for remote barcode reading, defect scanning on deep conveyor belts, and part alignment where the camera must remain safely clear of robotic movements. Its tight 10.5° horizontal span makes it highly valuable for CCTV long-range surveillance, such as single-lane gate access control, long hallway monitoring, and perimeter security. The compact M12 size combined with a 300mm minimum focus distance makes it particularly suited for analytical medical diagnostic equipment and benchtop laboratory cameras requiring strict spatial setups.
Compatible Device List

Frequently Asked Questions
- Q: What is the primary benefit of a 35mm focal length on an M12 lens?
- A: A 35mm focal length provides a narrow telephoto view (10.5° horizontal on a 1/2″ sensor). This lets you isolate a tight target area from a significant working distance, giving you a physical zoom advantage without large, heavy lenses.
- Q: Does this lens require digital software-based distortion correction?
- A: No, with a geometric distortion rating of less than 0.8%, this low distortion lens provides straight lines and true dimensions directly out of the box, saving valuable onboard processor power.
- Q: What type of filter is built into the lens?
- A: The “FILTER: Yes” specification indicates an integrated optical filter (typically an IR Cut Filter), which prevents color distortions caused by infrared light during daylight, ensuring precise visual contrast.
- Q: Can this 35mm telephoto lens focus on objects close by?
- A: Yes, despite being a long focal lens, it has a Minimum Object Distance (M.O.D.) of just 300mm (30cm). This allows it to double as a close-up macro lens for specific industrial components.
- Q: Is the iris adjustable for changing light levels?
- A: No, this lens has a fixed F2.8 aperture. It provides a reliable and consistent light throughput that is ideal for factory automation with fixed, stable artificial illumination.
- Q: Can I mount this lens onto a larger sensor like a 1/1.8″ or 2/3″?
- A: It is specifically optimized for a 1/2″ image circle. Mounting it on a larger sensor may result in vignetting (dark corners) because the sensor area extends past the intended light output of the lens.
