Frequently Asked Questions
Q: What makes an “F-Theta Low Distortion” lens different from a standard fisheye lens?
A: Standard fisheye lenses compress the edges heavily, causing severe bending. This f-theta lens keeps image height proportional to the angle, limiting geometric distortion to less than 3.78% for accurate measurements.
Q: Can this 5MP lens work on smaller sensors like 1/3-inch?
A: Yes, it is fully backward compatible with 1/2.7″ and 1/3″ sensors, though the final field of view will crop slightly based on the sensor dimensions.
Q: Does the 6G construction mean it is made entirely of glass?
A: Yes, the 6G construction uses 6 layers of precision-molded optical glass, ensuring high thermal stability, scratch resistance, and optimal light transmission.
Q: Is this lens suitable for outdoor security and drone applications?
A: Absolutely. The bright F2.0 aperture excels in low-light environments, and the rigid M12 fixed focal design handles high vibration on drones and vehicles excellently.
Q: What is the benefit of the 0.1m Minimum Object Distance (M.O.D.)?
A: It allows close-range machine vision cameras to focus clearly on objects just 10cm away while still retaining a massive panoramic view of the background.
Q: Do you provide custom modifications for the mechanical barrel or IR filters?
A: Yes, we offer OEM/ODM customization services to adapt the TTL, add specific IR-cut/pass filters, or change coatings based on your project requirements.
