Frequently asked questions
What sensors work with the CIL857 small 6mm M8 lens?
The CIL857 supports 1/2.7 inch sensors up to 5MP, including the Sony IMX335. Its 5.5mm designed image circle and 7.0mm total image circle cover standard 1/2.7 inch formats with margin.
What is the difference between the M8 and M12 variants of the CIL857?
The M8 variant uses M8x0.35 threads, weighs 0.8g, and targets ultra-compact cameras. The M12 variant uses M12x0.5 threads, weighs 2g, and fits standard S-mount camera hardware. Both versions share the same optics and 10.4mm total track length.
How much does the CIL857 M8 lens weigh?
The CIL857 M8 variant weighs 0.8g. The M12 variant weighs 2g. Both versions use aluminum barrels and BBAR coating on the first lens surface.
Is the CIL857 compatible with FLIR Blackfly S or Allied Vision cameras?
No. The CIL857 does not mechanically fit FLIR Blackfly S, Allied Vision Alvium, iDS uEye LE, or The Imaging Source M12 cameras because the package is too compact for those mounts. It does work with e-con Systems boards that use a 5-7mm holder and the Commonlands CLA819 mount.
Does the CIL857 ship same day from the US?
Yes. All in-stock CIL857 variants ship the same day from San Diego, California, when you order before 12 PM PST. Commonlands stocks both M8 and M12 versions with and without 650nm IRC filters.
What is the distortion of the CIL857 and is software correction needed?
The CIL857 has -2% TV distortion at the 5.5mm image circle. That level is low enough that most machine vision systems can use the image without software cleanup.
