Description
5MP 3.1mm M12 Wide Angle Lens
Expand your visual horizons with our high-resolution 5MP 3.1mm M12 wide angle lens. Perfectly engineered for 1/2.5″ format sensors, this compact board lens delivers a stunning 146° diagonal field of view, making it an exceptional choice for capturing sweeping landscapes or tight, comprehensive indoor spaces. Built with a precise 4G+1P+IR (4 Glass + 1 Plastic + IR filter) structure, it guarantees excellent light transmission, minimizes color aberrations, and provides optimal low-light performance with its F2.8 fixed aperture. Whether integrated into smart action cameras or industrial vision platforms, this lens offers reliability without compromising clarity.
Core Highlights
- Ultra-Wide 146° Diagonal FOV: Delivers expansive panoramic coverage that eliminates standard blind spots, ideal for single-camera environmental monitoring.
- 5-Megapixel Optical Resolving Power: Provides razor-sharp UHD imaging across the entire frame, preserving fine details for facial recognition and AI analytics.
- Low Distortion Optical Correction: Professionally engineered to keep optical distortion to a minimum (<-64% D), keeping geometric straight lines natural even at wide angles.
- Rugged 4G+1P+IR Component Structure: Combines four precision glass elements with a specialized plastic lens and integrated IR filter to withstand thermal shifts while blocking stray light.

Applications & Compatibility
This ultra-wide 5MP M12 board lens is purpose-built for space-constrained devices requiring maximum spatial awareness. It serves as an excellent component for drone & UAV aerial mapping, automotive dashcams, 360-degree surround-view vehicle monitoring, and smart video doorbells. With a remarkably short 0.1m minimum object distance, it excels in macro-to-wide inspection setups, making it highly valuable for warehousing AGV robotics and factory automation scanning lines. The fixed F2.8 aperture ensures stable exposures across unpredictable outdoor environments, maintaining image contrast during high-speed movement.

Q: What does the M12 x 0.5 mount mean?
A: This is a standard S-mount (board lens) interface with a 12mm thread diameter and a 0.5mm thread pitch. It is widely used in compact surveillance, automotive, and industrial action cameras.

Q: Can this lens cover a 1/2-inch sensor without vignetting?
A: This lens is specifically optimized for a 1/2.5″ maximum image format. Using it on a larger 1/2″ sensor may result in dark corners (vignetting), though it will work perfectly on smaller formats like 1/2.8″ or 1/3″.

Q: Is the focus adjustable on this lens?
A: The lens itself features a fixed focal length (3.1mm). However, the initial focus is adjusted manually by screwing the lens into the M12 mount thread of your camera module until the image is sharp, then locking it with an M12 lock ring.

Q: How does the optical distortion affect the security footage?
A: While all fisheye lenses feature distortion due to their wide field of view, this lens controls distortion remarkably well (<-64% D). The resulting image can easily be flattened or corrected digitally using standard software de-warping algorithms.
