Fisheye Lens – S6221120F – IMX577

S6221120F – IMX577 is 12-Megapixel Fisheye CCTV Lens with Built-In IR Filter, Φ6.2mm, F2.0, M12x0.5 mount, 211° diagonal FOV, for security surveillance.

M12 2.2mm 12MP Fisheye Lens

This 2.2mm M12 fisheye lens is designed for ultra-wide-angle imaging applications requiring up to 12MP resolution and an exceptionally broad 211° field of view. With a fixed F2.0 aperture, M12 × 0.5 mount, and 7G+IRCF optical structure, it is suitable for panoramic cameras, compact vision modules, robotics, drone imaging, and wide-area visual sensing.

The 211° field of view makes this lens particularly suitable for applications where a single camera needs to capture an exceptionally large scene. Engineers can use the FOV Calculator to evaluate coverage requirements based on sensor and installation geometry.

M12 2.2mm Fisheye Lens Applications

Core Application Scenes

This 12MP M12 fisheye lens is designed for imaging systems where maximizing scene coverage is more important than maintaining rectilinear geometry. Its 211° field of view allows a compact camera to capture an extremely large visual area, making it suitable for panoramic observation, spatial awareness, and wide-area monitoring.

The lens is particularly useful in compact panoramic camera modules, where a single optical system needs to cover areas that would otherwise require multiple conventional lenses. Its 2.2mm focal length and 0.2m minimum object distance also make it suitable for relatively close-range wide-area imaging, such as indoor spatial monitoring and robotic perception.

For robotics, the ultra-wide perspective can provide broad environmental awareness around a mobile platform, helping reduce blind zones during navigation. In drone and aerial imaging systems, the compact M12 format provides a practical option for capturing a large portion of the surrounding environment while maintaining 12MP image detail.

The lens can also be integrated into panoramic security and smart vision devices where wide scene coverage is required. For applications requiring further optical guidance, the Lens Selection Guide explains how focal length, sensor size, and field of view influence lens selection.

Frequently Asked Questions

Q: What is the field of view of this M12 fisheye lens?
A: When paired with the specified Sony IMX577 sensor, the lens provides a 211° diagonal FOV, 211° horizontal FOV, and 141° vertical FOV.

Q: Is this a fisheye lens?
A: Yes. The 211° field of view and F-Theta distortion characteristic indicate an ultra-wide fisheye optical design intended for very broad scene coverage.

Q: What resolution does this M12 fisheye lens support?
A: The lens is specified for 12MP imaging and is listed with the IMX577 sensor configuration.

Q: What is the focal length of this fisheye lens?
A: The focal length is 2.2mm, providing an exceptionally wide perspective for panoramic and environmental imaging applications.

Q: Does the lens have low distortion?
A: No. This lens is designed as a fisheye optic rather than a low-distortion lens. Its specified F-Theta distortion is below -19%, which supports its ultra-wide-angle imaging characteristics.

Q: What mount does this lens use?
A: The lens uses an M12 × 0.5 mount, making it suitable for compact embedded camera modules and other miniature imaging systems.

Q: What does IRCF mean in the optical structure?
A: IRCF refers to an IR Cut Filter configuration. It should not be interpreted as the same as an IR-corrected optical design. The actual spectral performance should be confirmed according to the specific camera module and application requirements.

Q: What applications are suitable for this 12MP fisheye lens?
A: Typical applications include panoramic cameras, robotics vision, drone imaging, wide-area monitoring, embedded AI vision, and other systems requiring extremely broad scene coverage from a compact camera.
