Frequently Asked Questions
- Q: Why is “<1% TV Distortion” crucial for mapping and industrial vision?
- A: Standard wide-angle lenses suffer from barrel distortion (curved lines). A TV distortion of less than 1% means this low distortion lens keeps straight lines straight, which is absolutely vital for accurate 3D mapping, measurement, and automated industrial inspection software.
- Q: What are the main benefits of the 7G all-glass structure over plastic lenses?
- A: Plastic lenses degrade, warp, and shift focus when heated up by direct outdoor sunlight or internal electronics. The 7G all-glass layout ensures incredible thermal stability across its -20°C to +80°C working range, ensuring your image stays perfectly sharp.
- Q: What type of filter is integrated into the “7G+IRCF” design?
- A: It includes a pre-installed IRCF (Infrared Cut Filter), typically a 650nm filter. This blocks unwanted infrared wavelengths during the day to ensure true-to-life, natural color accuracy for your 12.5MP video stream or photography.
- Q: Can this lens focus on objects that are very close?
- A: Yes. The Minimum Object Distance (M.O.D.) is only 0.2 meters (20cm / approx. 8 inches). This allows the lens to capture crystal-clear macro imagery, making it ideal for close-range assembly line scanning or robotic component tracking.
- Q: Will this lens fit a standard 1/2.5″ sensor camera module?
- A: Yes, it will work beautifully. Since its maximum image circle format is Max Φ9.1mm (1/2.3″), mounting it to a slightly smaller 1/2.5″ sensor will crop the field of view slightly but will yield outstanding edge-to-edge sharpness with zero vignetting.
- Q: Is the iris adjustable on this 12.5 Megapixel lens?
- A: No, it features a fixed iris locked at an aperture of F2.8. A fixed iris is highly preferred for automated industrial lenses and drone gimbals because it removes moving parts, ensuring maximum durability under high vibrations while your camera’s electronic shutter manages exposure dynamically.
