Are you tired of sifting through lens catalogs where "Wide Angle" usually means "Fish-Eye Distortion"? Or perhaps you're struggling to find a compact M12 lens that can actually handle the resolution of modern 1/2" sensors?

Stop compromising. It’s time to meet the JSD3122.

While the market is flooded with consumer-grade glass, the JSD3122 stands apart. This isn’t for your holiday snapshots; it’s a precision-engineered optical tool designed for high-end board cameras, industrial inspection, and advanced security systems.

Here is why this lens is the perfect balance of field of view and geometric precision.

1. Crushing the "3% Distortion" Standard

The industry standard for "low distortion" wide-angle lenses often hovers around 3% to 5%. That might be fine for a doorbell camera, but for machine vision and precise measurement, it’s not enough.

The JSD3122 doesn’t just meet the low-distortion requirement—it shatters it.
With an optical distortion rating of < -1.54%, this lens delivers exceptionally straight lines and true-to-life geometry. Whether you are running AI object detection or scanning barcodes, the JSD3122 ensures your software sees the world as it truly is, reducing the need for heavy image de-warping processing.

2. Big Sensor Power: 1/2" Image Circle

Most compact M12 (S-Mount) lenses are built for smaller 1/3" or 1/4" sensors. Putting those on a larger sensor results in ugly black corners (vignetting).

The JSD3122 is a beast in a small package. It features a robust 1/2" Image Circle, allowing it to pair perfectly with larger, high-performance industrial sensors. This means better light sensitivity, better dynamic range, and full coverage without the crop.

3. Crystal Clear 12MP Resolution

In the professional world, every pixel counts. The JSD3122 is rated for 12MP resolution, ensuring that your high-definition sensor is utilized to its full potential. From the center to the edge, the 3.94mm focal length delivers sharp, crisp details that are critical for identification and inspection tasks.

4. The Perfect Field of View

Balancing coverage and detail is an art. With a Field of View (FOV) of 92° (and capable of wide-angle coverage typically sought in the 100° class depending on sensor usage), the JSD3122 offers excellent situational awareness. It’s wide enough to monitor a full workspace or room, but tight enough to maintain high pixel density on your target.
