Frequently Asked Questions
Q: Can this 0.9mm lens be used with sensors larger or smaller than 1/3″?
A: It is perfectly optimized for 1/3″ sensors like the OV4689. Using it on a smaller sensor (e.g., 1/4″) will crop the field of view below 220°, while a larger sensor may cause dark corners (vignetting).
Q: Does this M12 fisheye lens feature a built-in IR cut filter?
A: Yes. The lens construction includes a 6G+IR cut filter, which effectively blocks infrared light during the day to prevent color casting, ensuring accurate color reproduction.
Q: Is the distortion profile acceptable for standard security use?
A: The lens has an optical distortion of <-169%, creating the classic “fisheye” effect. For security and AVM applications, this distortion is easily corrected via camera software dewarping algorithms to achieve a natural panoramic view.
Q: Can I adjust the aperture or focal length on this model?
A: No, this is a Fixed Focal Lens with a fixed F2.2 aperture. It is engineered this way to maintain stability, high vibration resistance, and a compact form factor.
Q: Does this lens support outdoor use in extreme weather?
A: Yes. Built with a 6G (six layers of glass) configuration and housing that meets ISO9001 standards, it offers excellent thermal stability compared to plastic lenses, preventing focus shift under direct sunlight or cold conditions.
Q: What is the benefit of the 0.1m M.O.D. parameter?
A: The Minimum Object Distance of 0.1 meters ensures that objects as close as 10 cm to the lens remain in sharp focus. This is crucial for video doorbells and industrial robotic arms tracking close-range items.
