2.56mm 4MP M12 Fisheye Lens for Ultra-Wide-Angle Imaging
This 2.56mm M12 fisheye lens is designed for ultra-wide-angle imaging where a standard camera lens cannot provide sufficient scene coverage. With a 165° diagonal FOV on the Sony IMX290 sensor and 4MP resolution support, it captures a broad field of view from a compact M12X0.5 optical package. The fixed F2.4 aperture and 6G optical construction provide a practical solution for embedded cameras, compact monitoring systems, and other space-constrained imaging devices. It is particularly suitable for applications that require maximum scene coverage from a short working distance.
For applications requiring a wider field of view, TOWIN also provides a range of wide angle lenses and M12 lenses for different sensor formats and camera designs.
Key Product Highlights
- 165° Diagonal FOV — The 165° diagonal field of view on the IMX290 provides extensive scene coverage, reducing blind areas in compact camera installations.
- 2.56mm Ultra-Short Focal Length — The short focal length is optimized for applications where maximum viewing coverage is more important than conventional perspective.
- 4MP Resolution Support — Provides sufficient image detail for compact monitoring and embedded vision systems requiring megapixel-level image output.
- Compact M12X0.5 Mount — The standard M12 thread simplifies integration into small camera modules where installation space is limited.
- Fixed F2.4 Aperture — Maintains a consistent optical configuration without requiring manual iris adjustment, simplifying camera module design.
M12 Fisheye Lens Applications
The combination of a 2.56mm focal length, extremely wide FOV, compact M12 mount, and 4MP resolution makes this lens particularly suitable for imaging systems that need to capture a large scene from a restricted installation position.
Core Applications
- Compact surveillance cameras — Suitable for cameras installed in confined indoor spaces where a conventional lens may leave excessive blind areas.
- Smart security cameras — The ultra-wide viewing angle can help monitor entrances, rooms, corridors, and other areas requiring broad scene coverage.
- Embedded vision devices — The compact M12 configuration makes the lens suitable for small camera modules integrated into electronic equipment.
- Panoramic and wide-area monitoring — The 165° diagonal FOV helps capture a substantially larger scene without requiring a long-distance installation position.
- Space-constrained imaging systems — The 14.5mm TTL and M12X0.5 mount are useful when optical packaging space is limited.
- Compact robotic or mobile vision devices — The wide-angle configuration can provide broader environmental awareness where camera size and field coverage are important.

Frequently Asked Questions
Q: What sensor size is this 2.56mm M12 lens designed for?
A: The lens has a 1/2.8″ image format and provides specified FOV performance on the Sony IMX290 sensor. It can also provide a 150° diagonal FOV when used with a 1/3″ 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 76° vertical FOV. The specified FOV changes with sensor format.
Q: What is the resolution of this M12 lens?
A: The lens is specified for 4-megapixel resolution, making it suitable for compact camera systems requiring megapixel-level image capture.
Q: What type of mount does this lens use?
A: It uses an M12X0.5 threaded mount, which is widely used for compact camera modules and embedded imaging systems.
Q: Does this lens have an adjustable iris?
A: No. The lens uses a fixed F2.4 aperture and fixed iris configuration, providing a consistent optical setup for camera module integration.
Q: What is the back focal length of this lens?
A: The specified B.F.L. is 4.38mm, while the total track length (T.T.L.) is 14.5mm.
Q: Can this lens be used for low-distortion machine vision inspection?
A: It is not recommended as a low-distortion inspection lens because its optical distortion is specified at less than -72%. Its strength is extremely wide scene coverage rather than geometric accuracy. For precision inspection, customers should consider TOWIN’s machine vision lens solutions and Distortion Guide.
