Frequently asked questions
What makes CIL327 different from a slower 2.7mm lens?
The main difference is speed. The CIL327 comes in F/1.5 and F/1.8 versions, so it passes more light than a typical slower 2.7mm wide-angle M12 lens.
What distortion is specified for CIL327?
The lens is specified at -13% F-Theta distortion at a 7.1mm image circle. That is what gives it a predictable ultra-wide mapping.
What sensor format is CIL327 designed for?
CIL327 is listed for a 1/2.6″ sensor format. That is the sensor class the 7.1mm image circle is meant to support.
What resolution is listed for CIL327?
The listed optical resolution is 3MP with 3μm pixels for the F/1.5 version. That version makes the most sense when low light matters more than chasing smaller pixels.
Is CIL327 ingress-protected?
Yes. The mechanical data lists the available version as IP67. That makes it suitable for exposed camera placements.
How heavy is CIL327?
The listed weight is 7g. That is still manageable for normal board-level camera mechanics.
