Description
2.5mm M12 Wide Angle Lens
Upgrade your optical system with our high-performance 2.5mm M12 wide angle lens. Engineered for 1/2.8″ image sensors, this 2 MegaPixel mini lens delivers an expansive 158° diagonal field of view and an F2.1 large aperture for exceptional low-light clarity. Designed without an IR cut filter (Without IRCF), it offers maximum light transmission, making it the perfect choice for night vision security, automotive backup cameras, and advanced industrial machine vision applications.
Key Features & Highlights
- 158° Ultra-Wide Field of View: Captures a sweeping panoramic perspective with a 129° horizontal FOV, drastically reducing blind spots in security and automotive monitoring.
- 2MP Full HD Clarity: Optimised for 2 MegaPixel 1/2.8″ CMOS sensors to deliver crisp, high-contrast imagery with minimal edge degradation.
- F2.1 Large Aperture Performance: Maximises light intake for superior imaging in low-illumination and night-vision environments.
- Compact M12 Mount Design: Standard M12x0.5 thread with a short 20.98mm total track length (T.T.L.) ensures seamless integration into space-constrained devices.
- Without IRCF for Night Vision: The omission of an internal IR cut filter allows maximum infrared light sensitivity, perfect for dual-day/night or dedicated IR illumination systems.

Target Applications & Compatible Devices
Core Applications
This ultra-wide M12 fisheye lens is custom-engineered for environments demanding an expanded field of view within a compact form factor. It excels in automotive surround-view systems (AVM) and electronic rearview mirrors, providing drivers with complete situational awareness. In smart home ecosystems, it serves as the optical core for smart video doorbells and wide-angle peephole cameras, capturing full-length porch views without blind spots. Additionally, its high 2MP resolution makes it highly effective for UAV/drone navigation cameras, warehouse automated guided vehicles (AGVs), and industrial factory automation where wide-angle scanning or robotic sorting requires a robust, fixed-focal miniature lens.
Device Compatibility List
- Sensors: Fully compatible with mainstream 1/2.8″ and 1/3″ CMOS image sensors (e.g., Sony IMX series, OmniVision, SmartSens).
- Security Hardware: Direct fit for Tuya IoT smart cameras, Xiaomi smart doorbells, and Hikvision/Dahua low-profile dome network modules.
- Industrial & AI Hardware: Seamlessly integrates with Raspberry Pi camera modules, Jetson Nano vision kits, and various USB machine vision camera boards.
- Customisation: Supports custom modifications for optical filters, focal lengths, and FOV adjustments to match specific OEM/ODM hardware requirements.

Frequently Asked Questions
Q: Does this lens have a built-in IR cut filter?
A: No, this lens features a “Without IRCF” structure. It passes both visible and infrared light, making it ideal for dedicated infrared night vision cameras or devices that use an external IR-cut switcher mechanism.

Q: Can I use this 1/2.8″ lens on a 1/3″ sensor?
A: Yes, it is fully compatible with smaller sensor sizes like 1/3″ or 1/4″. Please note that using a smaller sensor will slightly reduce the effective field of view (FOV).
A: Yes, it is fully compatible with smaller sensor sizes like 1/3″ or 1/4″. Please note that using a smaller sensor will slightly reduce the effective field of view (FOV).
Q: Is the M12 mount compatible with standard action cameras or dashcams?
A: Yes, it uses a standard M12x0.5 thread pitch (S-mount), which is the industry standard for dashcams, action cameras, CCTV dome cameras, and webcams.
A: Yes, it uses a standard M12x0.5 thread pitch (S-mount), which is the industry standard for dashcams, action cameras, CCTV dome cameras, and webcams.
Q: What does the <-19% TV distortion mean for my image?
A: A TV distortion value of <-19% indicates a barrel distortion, which creates the classic “fisheye” effect. This is mathematically expected and ideal for maximizing the visual coverage area up to 158°.
