220° Stereographic Fisheye M12 Lens for 1/3" Board Cameras

The CIL207 is a 220° stereographic M12 fisheye lens built for 1/4" to 1/3" sensors like the IMX226 and AR0821. At 0.8mm EFL, F/1.9, and only 4g, it packs more field of view into a smaller package than nearly any lens in its class. The 2G4P optical design resolves 3–5MP at 2.2μm pixel pitch across a 4.0mm image circle.

Stereographic projection is the right choice when edge detail matters. Unlike equidistant fisheye lenses, stereographic maintains more uniform angular magnification across the frame — objects near the periphery stay closer to their true relative size. The +27% F-Θ figure places the CIL207 firmly in stereographic territory, which is what makes it strong for exterior surveillance, drone downward-facing cameras, and wide-area inspection where you can't afford to lose resolution at 90° off-axis.

The M12A variant ships IP67-rated with a sealed metal barrel and BBAR coating on the first lens surface. Order CIL207-F1.9-M12A650 with the 650nm IRC filter for standard daylight use, or CIL207-F1.9-M12ANIR for NIR-sensitive sensors. e-con Systems S-mount boards need a 5–7mm tall holder. Allied Vision Alvium and FLIR Blackfly S board-level cameras are not mechanically compatible without a custom adapter.
