Frequently asked questions

What sensors does the CIL529 4mm C-mount lens support?

The CIL529 is listed for 2/3 inch sensors up to 5MP, including the Sony IMX546. The focal length is 4mm and the maximum aperture is F/2.8.

What is the field of view of the CIL529?

The CIL529 covers 106° at its 11mm image circle. Use the Commonlands field of view calculator to find the angle for your sensor.

How much distortion does the CIL529 have?

Measured distortion is about -3%, which is low for a 106° wide-angle lens. Calibrate the image if the system measures across the full frame.

Is the CIL529 in stock?

Not always. The page says Commonlands tries to restock quickly and asks customers to contact for availability. Check the live page before planning around immediate delivery.

Is the CIL529 an M12 lens?

No. The CIL529 is a C-mount lens. Use it with cameras that support the 1 inch-32 C-mount thread and the standard 17.526mm flange distance.

When should I choose the CIL529?

Choose the CIL529 when you need a wide 4mm field of view on a 2/3 inch 5MP global shutter camera with distortion held low for the angle.

The CIL529 is a 4mm C-mount lens for sensors up to 2/3-inch, including 5MP formats like the Sony IMX546. At 4mm it is a wide-angle lens that takes in a large scene from a short distance, which fits overhead inspection, bin picking, and wide-area industrial machine vision.

The lens is built for global shutter cameras and holds low distortion for its angle of view. It covers an 11mm image circle with a 106° field of view, and measured distortion is about -3%. For a 106° lens that is well controlled, but a wide-angle optic still benefits from calibration if the system takes measurements across the full frame.

The listed part number is CIL529-F2.8-CMANIR, F/2.8, without filter, C-Mount A. The optical construction is hybrid glass and plastic in a metal barrel, which keeps weight down on a wide lens. This part is not always in stock, so check the live page or contact Commonlands before you plan a build around immediate delivery.

Choose the CIL529 when you need a wide 4mm field of view on a 2/3-inch 5MP global shutter C-mount camera and want distortion held low for the angle. Confirm the camera uses the 1"-32 C-mount thread and 17.526mm flange distance before ordering.
