Our take on the 190° Compact M8 / M12 Fisheye Lens

The CIL818 is a 1.8mm fisheye lens for small camera modules, sold in M8 and M12 barrel formats. It gives a 200° field of view on a 5.25mm image circle with an F/2.0 aperture, and both barrel versions are IP67-rated for dust and water resistance. That combination of a very wide view, a fast aperture and sealed construction suits embedded cameras in tight or exposed spots. Compared with typical M12 fisheye lenses, which often stop around 180° and are rarely sealed, it trades some edge sharpness for coverage and weather protection.

Questions and answers

What sensor size does the 5.25mm image circle fit?
The lens projects a 5.25mm image circle, so it pairs with small sensors whose diagonal fits inside that circle. Larger sensors will vignette or crop the view.
Is the M8 version also IP67?
Yes. Both the M8 and M12 barrel formats are IP67-rated, so the sealing does not depend on which mount you pick.
How wide is 200° compared with a 180° fisheye?
It captures roughly 20° more across the frame than a 180° fisheye, which helps when the camera sits close to a wall or in a corner. Expect more distortion to correct.
Does it focus automatically?
No. It is a manual-focus lens, so you set focus on the camera module and lock it in place.
What is the F/2.0 aperture good for?
It lets in more light than slower fisheye lenses, which helps in dim rooms and keeps exposure times shorter for moving subjects.
Where is the 190° Compact M8 / M12 Fisheye Lens cheapest?
At Amazon, for $35.00, as of our latest check.
