M12 Wide Angle Lens for up to 12MP 1/2" such as IMX477 and IMX412

The CIL330 is a 2.9mm wide-angle M12 lens for 1/2" sensors up to 12MP, including the Sony IMX477 and IMX412. It gives you a 120° field of view and an 8.0mm image circle, so the coverage lands in GoPro territory without forcing you into a fisheye workflow. The fixed F/2.6 aperture also leaves enough light on the sensor for real embedded vision work.

The distortion is -3% F-Θ, which keeps angular resolution nearly constant from center to edge. That is useful for SLAM navigation, panoramic stitching, and surveillance, because the pixels per degree stay more consistent across the frame.

Both variants ship with IP67 sealing, aluminum barrels, and BBAR coating. The M12A has 3.6mm mechanical back focal length, while the M12B has 4.4mm MBFL. Pick the version that matches your camera board stack height. If you need daylight imaging, order the 650nm IRC filter. If you need night vision or multispectral work, order the NIR version. Total weight is 7g.

The CIL330 fits Commonlands CLA024 holders, FLIR Blackfly S, Allied Vision Alvium, iDS uEye XLS, The Imaging Source M12, and Basler Dart. e-con Systems boards need an 8-13mm tall M12 holder.
