Frequently Asked Questions
-
- Q: What are the main benefits of the 6G all-glass construction?
-
- A: All-glass optics provide maximum light transmission, resist scratches, and prevent focus shifting (thermal drift) when the camera heats up or operates in extreme outdoor weather environments.
-
- Q: How does this lens perform when mounted on a 1/2.7″ sensor?
-
- A: It performs exceptionally well. The 1/2.7″ sensor will capture a slightly narrower field of view (104° diagonal instead of 112°), but it will benefit from pristine edge sharpness since it utilizes the center sweet spot of the lens.
-
- Q: Does the lens feature an integrated IR filter?
-
- A: Yes, it includes a built-in IRCF (IR Cut Filter) to filter out unwanted infrared light during daylight, ensuring accurate color rendering and vivid daytime imagery.
-
- Q: Can this lens be used with external infrared LEDs for night vision?
-
- A: Yes. The bright F1.8 aperture allows excellent low-light absorption, making it highly effective when paired with standard dual-light or day/night security modules that swap lighting spectrums.
-
- Q: Is the focal length adjustable on this lens?
-
- A: This is a fixed focal lens (4mm). Focus distance is adjusted during mechanical installation by screwing the M12 mount into your camera module’s bracket until the image becomes sharp, then locking it down.
