Frequently Asked Questions
-
- Q: What are the advantages of the 4G+3ASPG optical structure?
-
- A: The combination of 4 Glass elements and 3 Aspheric Plastic elements offers the perfect balance of excellent thermal stability, superb edge-to-edge sharpness, and a lightweight design, while drastically reducing optical aberrations common in wide-angle lenses.
-
- Q: Can this lens fit smaller sensors like 1/2.8″ or 1/3″?
-
- A: Yes, with its Max Φ9.1mm image circle, it can easily fit smaller sensors. However, please note that the field of view will crop proportionally to the sensor size.
-
- Q: Does this lens include an infrared cut filter?
-
- A: Yes, it features an integrated IRCF (IR Cut Filter), which blocks infrared light during daytime to deliver accurate colors and high contrast.
-
- Q: Is the <-89% distortion normal for this lens?
-
- A: Yes. This is a design characteristic of ultra-wide fisheye lenses to map a 176° panoramic field of view onto a flat image sensor. The distortion can be corrected via camera software or dewaping algorithms if a flat perspective is needed.
-
- Q: Is this lens rugged enough for outdoor and automotive environments?
-
- A: Absolutely. Thanks to its glass-plastic hybrid structure and standard M12 industrial threading, it handles mechanical vibrations and temperature fluctuations reliably when properly housed.
