Frequently asked questions
What sensors work with the CIL326 2.9mm M12 lens?
The CIL326 fits 1/2.7 inch sensors up to 3MP, including the Sony IMX322 and IMX390. Its 6.8mm designed image circle covers those formats with margin.
How wide is the CIL326 field of view?
The CIL326 gives 146° field of view at the 6.6mm image circle. You can check the exact horizontal and vertical angles for your sensor at field of view calculator
Is the CIL326 good for automotive surround-view cameras?
Yes. The F/1.45 aperture and 146° field of view make the CIL326 a strong choice for automotive surround-view, in-cabin monitoring, and other ADAS cameras that need wide coverage in low light.
What is the distortion on the CIL326 M12 lens?
The CIL326 has -8% F-Theta distortion at 6.6mm. That level is typical for a wide automotive lens, and most ADAS software pipelines can correct it.

Yes. Orders placed before 12 PM PST ship same day from Commonlands in San Diego, California.
What lens holder works with the CIL326?
The Commonlands CLA020 holder is one compatible mount for the CIL326, and other M12 mounts work as well. The lens also fits e-con Systems boards with a 13mm tall mount, Allied Vision Alvium, FLIR Blackfly S, iDS uEye XLS, The Imaging Source M12, and Basler Dart cameras.
