Frequently asked questions
What sensors work with the CIL829 2.8mm M8 lens?
The CIL829 supports 1/2.8 inch sensors up to 3MP with 3μm pixel pitch, including the ON Semiconductor AR0230. Its 6.4mm designed image circle, with 7.0mm maximum, covers those formats with margin.
How much distortion does the CIL829 have?
The CIL829 has -1% distortion from rectilinear. That is unusually low for a 100° field of view lens, so it works well for barcode reading, obstacle detection, and visual SLAM where geometry matters.
What is the difference between M08A and M12A mount options on the CIL829?
The M08A uses an M8x0.35 thread and weighs 1.4g, while the M12A uses the standard M12x0.5 thread. The optics stay the same, so you choose M8 for minimum size and M12 for standard S-mount compatibility.
Is the CIL829 suitable for drone or embedded vision applications?
Yes. The 1.4g M8 version fits drones, wearables, and compact embedded vision modules where every gram matters.
What is the chief ray angle on the CIL829?
The CIL829 has a 21° chief ray angle. You should compare that value with your sensor's microlens CRA specification because a large mismatch can create color shading at the edges. Read more at CRA mismatch guide
Does the CIL829 ship same day from the US?
Yes. Commonlands ships in-stock lenses same day from San Diego for orders placed before 12 PM PST.
