Frequently Asked Questions
Q: Can this 6MP M12 lens be used on smaller sensors like 1/2.8″?
A: Yes, it is fully backward compatible. However, because a 1/2.8″ sensor is smaller than a 1/1.8″ sensor, the outer edges of the frame will be cropped, making your final field of view narrower than the listed IMX178 specifications.

Q: How does the <-35% optical distortion affect my AI recognition software?
A: At <-35%, this lens provides a noticeably flatter, less distorted image than standard 170° fisheye lenses. For general CCTV lens use or traffic flow checking, it can be used directly without dewarping. For precise FA lens industrial measurements, it can be easily calibrated out using standard OpenCV grid scripts.

Q: Does this lens include a built-in IR cut filter (IRCF)?
A: Yes, the optical structure is 6G+IRCF, meaning it features an integrated Infrared Cut Filter. This filters out infrared noise during daylight to guarantee vibrant, realistic colors for outdoor surveillance.

Q: Is the manual focus ring secure enough to handle vehicle or drone vibrations?
A: Absolutely. The Manual Focus threading has excellent precision and tight tolerances. For intense vibration scenarios like drone & UAV lenses or automotive lens deployments, we recommend securing the threads with a standard M12 locking ring or optical thread glue.

Q: What are the benefits of the F1.8 aperture in this wide angle lens?
A: An F1.8 aperture allows significantly more light to reach the sensor than standard F2.0 or F2.4 lenses. This allows your camera sensor to use faster shutter speeds or lower gain (ISO) settings, dramatically reducing nighttime image noise and motion blur.
