The world of compact optics has stuck to a status quo for too long. For years, if you wanted an M12 (S-Mount) lens, you often had to compromise. You could have compact size, or you could have high performance—but rarely both.

Today, that changes.

We are proud to announce the official release of the JSD3122, a lens that doesn’t just meet the standard—it shatters it. This is not a lens for average consumer gadgets or budget webcams. This is an optical powerhouse engineered specifically for the rigorous demands of professional industrial, security, and automotive systems.

Here is how the JSD3122 is rewriting the rulebook for M12 optics.

1. 12MP: The New Definition of Clarity

In an era where "HD" is no longer enough, the JSD3122 steps up with 12MP Resolution.
Most M12 lenses top out at 5MP or 8MP, leaving modern high-res sensors starved for detail. The JSD3122 delivers edge-to-edge sharpness that supports true 4K imaging and beyond. Whether you are detecting microscopic defects on a production line or reading license plates at a distance, this lens resolves every pixel your sensor captures.

2. Breaking the Size Barrier: 1/2" Sensor Support

This is the feature that has engineers talking. Traditionally, M12 lenses are designed for small 1/3" or 1/4" sensors.
The JSD3122 breaks this physical limit by covering a massive 1/2" Image Circle.

Why does this matter? It allows you to pair this compact lens with larger, high-sensitivity sensors (like the Sony IMX series). You get the low-light performance and dynamic range of a bulky C-mount system, all within the tiny footprint of an M12 lens.

3. Precision Without the Bend (Distortion < -1.54%)

Wide-angle lenses usually come with a penalty: the "fish-eye" effect.
The JSD3122 offers a broad 92° Field of View (EFL 3.94mm), but it keeps the world looking the way it should. With optical distortion controlled to <-1.54%, lines remain straight and geometry stays true. This "Linear" performance is critical for AI algorithms that rely on accurate shape recognition, eliminating the need for processor-heavy image de-warping.

4. Compact Engineering Marvel

Fitting this much glass into a small package is an engineering feat.

TTL (Total Track Length): Just 20.49mm.

Aperture: A fast F/2.2 for superior light intake.

Mount: Standard M12 Thread.

It is designed to slip seamlessly into compact industrial housings, drone gimbals, and discreet security units where space is at a premium.

5. Built for the Pros

Let’s be clear: The JSD3122 is a serious tool for serious applications. It is not designed for the consumer camera market. It is built for:

Advanced Machine Vision

Intelligent Transportation Systems (ITS)

High-End Biometrics

Industrial Inspection

The New Standard is Here

The release of the JSD3122 marks a new chapter in compact optics. It proves that you don’t need a massive lens to get massive performance.
