2.4mm 4MP M12 fisheye lens with 165° FOV for 1/2.8″ IMX290 sensors, designed for compact ultra-wide-angle imaging systems.
This 2.4mm M12 fisheye lens is designed for compact imaging systems that require an extremely wide field of view in a small installation space. With a 165° diagonal FOV, 140° horizontal FOV, and 75° vertical FOV on the Sony IMX290 sensor, it captures a broad scene with a single camera. The 4MP optical resolution, F2.4 fixed aperture, and 0.2m minimum object distance make this fixed focal lens suitable for applications requiring wide-area scene coverage, close-range monitoring, and compact camera integration.
For systems requiring a compact M12 lens, this model combines a 2.4mm focal length with an ultra-wide-angle optical design and 16.5mm total track length. Its manual focus structure and fixed iris simplify mechanical integration while maintaining a compact optical configuration.

Core Applications
This M12 fisheye lens is particularly suitable for imaging systems where a very wide viewing area is more important than low geometric distortion. The 2.4mm focal length and 165° diagonal FOV make it suitable for compact security cameras, smart monitoring devices, indoor panoramic or near-panoramic imaging, small embedded cameras, and other wide-area observation systems.
Its compact 16.5mm T.T.L. and M12×0.5 mounting interface are advantageous for devices with limited internal installation space. The 0.2m M.O.D. also supports close-range monitoring where the camera needs to cover a large area from a short distance.

Designed for ultra-wide-angle surveillance and compact wide-area imaging applications.
Q: What sensor size is this 2.4mm M12 fisheye lens designed for?
A: This lens is designed for a 1/2.8″ image format and provides the specified FOV performance when used with the Sony IMX290 sensor.
Q: What is the field of view of this M12 fisheye lens?
A: With the IMX290 sensor, the lens provides a 165° diagonal FOV, 140° horizontal FOV, and 75° vertical FOV.
Q: Is this a low distortion lens?
A: No. The optical distortion is specified as less than -83%, which is characteristic of an ultra-wide-angle fisheye optical design. This lens prioritizes maximum scene coverage rather than geometrically corrected imaging.
Q: What is the mount of this fisheye lens?
A: The lens uses an M12×0.5 mount, making it suitable for compact camera modules and embedded imaging systems with an M12 interface.
Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.2m, allowing the lens to be used for relatively close-range wide-area imaging applications.
Q: Does this lens have adjustable focus or zoom?
A: The lens uses manual focus and a fixed focal length. It does not provide optical zoom adjustment.
Q: What is the aperture of the 2.4mm M12 lens?
A: The lens has a fixed F2.4 aperture, providing a consistent optical configuration for compact wide-angle imaging systems.
Q: Can TOWIN customize this type of M12 fisheye lens?
A: TOWIN can evaluate customized optical requirements such as focal length, sensor format, field of view, mounting interface, and mechanical dimensions based on project requirements. Contact TOWIN to discuss your application.
