M12 3mm F2.0 Manual focus JSD3020 12MP M12 Wide-Angle Lens – 121° FOV F2.0 for Sony IMX334

The JSD3020 is a 12MP M12 ultra-wide angle imaging lens developed for camera module manufacturers and embedded vision teams building products around large-format 1/1.8" and 1/1.7" sensors. With an effective focal length of 3.05mm, it provides a wide field of view — roughly 121° diagonal on a 1/1.7" sensor and 119° on a 1/1.8" sensor — a specification frequently chosen for video conferencing, live streaming, and indoor security cameras where one module must cover an entire room without the cost, alignment effort, and processing overhead of multi-camera stitching.

For module teams developing conference and surveillance cameras, a wide angle is only half the challenge; the optic also has to keep up with the sensor. Inexpensive all-plastic wide-angle designs often show softened edges and visible color fringing when scaled up to large-format 12MP sensors. The JSD3020 approaches this with a hybrid 4G4P construction: four glass elements paired with four aspheric plastic elements. The glass group contributes thermal stability and more consistent imaging in around-the-clock environments, while the aspheric elements help manage aberration and distortion within a compact 29.56mm total track length. At F2.0, the aperture transmits enough light for practical output in dimly lit conference rooms, lobbies, and corridors, reducing reliance on supplemental lighting.

Measured at approximately φ22mm in diameter and about 8g in weight, the lens is sized for space- and weight-constrained camera modules — a factor that matters when optical engineers are balancing thermal management, mounting, and housing constraints around a large sensor. The JSD3020 supports both 1/1.8" and 1/1.7" sensor formats, including Sony IMX334- and IMX477-class devices, giving design teams flexibility in their sensor roadmap and simplifying qualification across a product line. For applications where the catalog configuration does not fully match the target, JSD provides custom optical development, and the engineering team can discuss mechanical interface changes, specialized coatings, and sensor-specific tuning.
