This 2.6mm M12 fisheye lens is designed for compact camera systems requiring an exceptionally wide field of view from a small optical module. With a 182° diagonal FOV, 129° horizontal FOV, F2.8 aperture, and M12×0.5 mount, it provides extensive scene coverage for panoramic surveillance, compact security cameras, and embedded wide-area imaging systems.
The 182° diagonal FOV is the defining feature of this lens, making it suitable for systems where maximizing scene coverage is more important than maintaining conventional rectilinear image geometry. Engineers can use the FOV Calculator when evaluating coverage requirements for different sensor and installation configurations.
This 2.6mm M12 fisheye lens is designed for applications where a single compact camera needs to observe an exceptionally large surrounding area. Its 182° diagonal field of view provides near-hemispherical scene coverage, making it particularly useful for panoramic monitoring and cameras installed in locations where minimizing blind areas is a primary requirement.
For 360°-style indoor monitoring, the lens can be integrated into compact cameras positioned in rooms, retail environments, entrances, corridors, and other areas requiring broad visual awareness. The 129° horizontal FOV allows substantial lateral coverage from a single camera position, while the 2.6mm focal length maintains the compact optical configuration.
The lens is also suitable for compact security and smart-device cameras where installation space is limited but a very wide viewing angle is required. Its M12×0.5 mount and 15.7mm TTL make it appropriate for camera designs where optical and mechanical dimensions need to be carefully controlled.
In robotics and embedded vision, the exceptionally wide FOV can provide broad environmental awareness around a device, helping a compact camera observe a large portion of its surroundings. Because the design prioritizes extreme field coverage, however, the specified distortion should be considered for applications requiring accurate geometric representation.
Designed for ultra-wide panoramic surveillance, smart camera, and broad-area embedded imaging applications.

Q: What type of lens is this 2.6mm M12 lens?
A: It is a fixed focal length M12 fisheye lens designed for extremely wide scene coverage, providing a 182° diagonal field of view with the specified 1/2.7″ image format.
Q: What is the field of view of this 3MP M12 fisheye lens?
A: The lens provides a 182° diagonal FOV, 129° horizontal FOV, and 92° vertical FOV when used with the specified 1/2.7″ image format.
Q: What image format does this lens support?
A: The lens has a maximum image format of Φ6.9mm, with the specified FOV based on a 1/2.7″ sensor format.
Q: Why is the distortion relatively high on this lens?
A: The specified TV distortion of less than -39% is a characteristic of the extremely wide-angle optical design. The lens prioritizes very broad scene coverage rather than rectilinear image geometry.
Q: Is this a low distortion lens?
A: No. The specified distortion of less than -39% means it should be positioned as a fisheye or ultra-wide-angle lens rather than a low distortion lens.
Q: Does this M12 lens have optical zoom?
A: No. It uses a fixed 2.6mm focal length and fixed zoom configuration, making it suitable for fixed-view imaging applications.
Q: What applications benefit from a 182° field of view?
A: Panoramic surveillance, room monitoring, retail observation, smart home cameras, embedded IoT vision, and robotic environmental awareness can benefit from its exceptionally broad field of view.
Q: How can I check whether the 182° FOV is suitable for my camera installation?
A: The required coverage depends on the sensor dimensions, focal length, and installation distance. The FOV Calculator can help estimate the expected field of view for a specific camera configuration.
When selecting a fisheye or ultra-wide-angle lens, engineers should consider field of view together with sensor format, image circle, distortion, aperture, and installation distance. The Lens Basics section provides additional information about fundamental optical parameters.
For applications requiring extremely broad coverage, the FOV Calculator can help engineers evaluate how focal length and sensor format influence the final viewing area.
The Distortion Guide can also help users understand the trade-off between extreme wide-angle coverage and geometric distortion.
