Description
Enhance your optical system with our premium 8MP 4.2mm M12 Low Distortion Lens. Specifically engineered for 1/2.5″ large format sensors, this high-performance wide angle lens delivers exceptional 8 Megapixel clarity with an impressive <3.8% low distortion profile. Featuring a robust 7G (all-glass) construction and a compact M12x0.5 mount, it is the ideal choice for developers seeking uncompromising image precision in demanding machine vision, CCTV, and industrial FA applications.
Product Highlights
- 8MP Crystal-Clear Resolution: Resolves fine details without blurring, perfectly matching 4K high-density sensors to prevent pixel-dropping in critical inspection tasks.
- Ultra-Low Optical Distortion: Keeps image geometric distortion under 3.8%, eliminating the severe “fish-eye” bending common in wide-angle lenses to ensure precise edge-to-edge measurements.
- Optimized 1/2.5″ Sensor Format: Offers a generous 83° diagonal field of view, maximizing sensor utilization on 1/2.5″, 1/2.7″, and 1/3″ CMOS chips without dark corners or vignetting.
- Rugged All-Glass 7G Construction: Utilizing 7 layers of precision-coated glass elements to guarantee high thermal stability, optimal light transmission, and zero degradation under harsh industrial environments.

Frequently Asked Questions
Q: Does this 8MP M12 lens support day and night imaging with IR lighting?
A: This lens is built with a high-performance 7G all-glass construction that provides excellent light transmission. Depending on your project requirements, it can be ordered with a standard 650nm IR-cut filter for daytime color fidelity or a dual-band/no-filter option for infrared night vision integration.
Q: What makes this “Low Distortion” compared to standard wide-angle lenses?
A: Standard 4.2mm lenses often exhibit noticeable barrel distortion (image bending at the edges). This lens uses an advanced 7-element optical design to suppress geometric distortion to less than 3.8%, ensuring lines remain straight for algorithm-based image processing.
Q: Can I use this 1/2.5″ format lens on a smaller 1/3″ CMOS sensor?
A: Yes, it is fully backward compatible with smaller sensor sizes such as 1/2.7″, 1/2.8″, and 1/3″. Please note that using a smaller sensor will result in a narrower crop factor (smaller Field of View) than the rated 83°(D).
Q: Is the iris adjustable for changing light conditions?
A: No, this lens features a Fixed Iris at F2.8. This fixed design maximizes mechanical reliability, lowers cost, and is ideal for environments where light levels are controlled or managed via camera electronic shutter speed.
Q: Does the lens come with a pre-installed mount holder?
A: This product listing is for the optical lens element only, featuring a standard M12x0.5 thread. We can provide matching lens holders or mount adapters separately upon request.
Q: Is this lens compliant with environmental and quality standards for global export?
A: Yes, our manufacturing processes are ISO9001 certified, and this specific lens is fully compliant with RoHS directives, making it cleared for seamless import and distribution in the EU and American markets.
