Frequently asked questions
What sensors does the CIL125 12mm M12 lens support?
The CIL125 covers sensors up to 1/2 inch format. At F/2.4 it resolves 12MP at 1.55μm pixel pitch, at F/3.6 it resolves 8MP at 1.85μm, and at F/8.0 it resolves 3MP at 3μm. Its 8.0mm image circle covers 1/2 inch sensors with margin.
What is the difference between the CIL125 F/2.4, F/3.6, and F/8.0 variants?
All three versions use the same 12.5mm optical design. The F/2.4 version gets the most light and resolves 12MP, the F/3.6 version is the middle ground at 8MP, and the F/8.0 version gives the deepest depth of field at 3MP. Compare them at depth of field calculator
How much distortion does the CIL125 telephoto M12 lens have?
The CIL125 keeps distortion to -1.4% rectilinear across its 35° field. That is low enough for license plate recognition, inspection, and measurement work.
Is the CIL125 compatible with Raspberry Pi HQ Camera?
Yes, the CIL125 works with the Raspberry Pi HQ Camera through M12 mount. The F/2.4 variant resolves the full 12MP of the IMX477.
Does the CIL125 telephoto M12 lens ship from the US?
Yes, in-stock CIL125 lenses ship same day from San Diego, California for orders placed before 12 PM PST.
What cameras are mechanically compatible with the CIL125?
The CIL125 is mechanically compatible with FLIR Blackfly S, Allied Vision Alvium, iDS uEye XLS, The Imaging Source M12, Basler Dart, and e-con Systems boards. works with the Commonlands CLA024 holder and other compatible mounts.
