Wide Angle Lens – S04012808510

S04012808510 is Wide angle Low Light Sensitive 8-Megapixel lens, 4.0mm focal distance 1/2.8″ M12 mount 102°(D) F1.0 security surveillance.

M12 4mm 8MP F1.0 Wide Angle Lens

This 4mm M12 wide angle lens is designed for 1/2.8″ image sensors such as the Sony IMX415, delivering up to 8MP resolution and a 102° diagonal field of view. With its fast F1.0 aperture, the lens is optimized for wide-area imaging and applications that require strong light-gathering capability in challenging or low-light environments.

The lens combines a compact M12 interface with an F1.0 aperture and wide viewing angle, making it suitable for camera modules that need to capture a large scene while maintaining high image brightness. Engineers can use the Sensor Guide when evaluating compatibility between the lens, sensor format, and imaging requirements.

• 102° Wide FOV: Covers a broad scene from a relatively compact camera position.
• M12 × 0.5 Mount: Supports compact embedded camera and vision module designs.
• IRCF-Free Structure: Without an integrated IR cut filter for application-specific optical configurations.

M12 4mm Wide Angle Lens Applications

Core Application Scenes

This M12 4mm F1.0 wide angle lens is designed for camera systems that need to combine broad scene coverage with high optical brightness. Its 102° diagonal FOV allows a single camera to monitor a relatively large area, while the F1.0 aperture provides substantially greater light-gathering capability than slower compact lenses.

The lens is particularly suitable for nighttime and low-light smart camera applications, where maintaining image brightness is important for identifying objects and capturing scene information. It can also be used in compact security cameras, embedded monitoring modules, and wide-area vision systems where the camera has a fixed installation position and needs to cover a broad viewing zone.

The lens uses a 1/2.8″ format and is specified with the Sony IMX415 for its FOV calculation. This makes it suitable for high-resolution camera modules that require an 8MP imaging capability without moving to a larger optical format.

Its Without IRCF structure is also important for system designers. Because the lens does not include an integrated IR cut filter, the final camera optical stack can be configured according to the specific imaging architecture, filter requirements, and intended spectral response.

For projects where the required viewing coverage needs to be estimated from working distance and sensor dimensions, the FOV Calculator can be used to evaluate the optical geometry before final lens selection.

Compatible Device List

• 8MP Security Camera Modules: Suitable for compact high-resolution cameras requiring wide scene coverage and a fast F1.0 aperture.
• Low-Light Surveillance Cameras: The large aperture helps maximize the amount of light reaching the sensor in dim environments.
• Embedded Vision Cameras: The M12 × 0.5 mount allows integration into compact camera modules and embedded imaging equipment.
• Smart Monitoring Devices: Suitable for fixed-position cameras that need to monitor a relatively broad area from a limited installation location.
• High-Resolution IoT Cameras: The combination of 8MP resolution and F1.0 aperture supports demanding networked imaging applications.
• OEM Camera Modules: The absence of an integrated IRCF allows system developers to determine the appropriate filter configuration for their own camera architecture.

Frequently Asked Questions

Q: What sensor is this 4mm M12 lens designed for?
A: The lens is designed for 1/2.8″ image sensors, with the specified field of view based on the Sony IMX415 sensor.

Q: What is the field of view of this M12 lens?
A: With the specified IMX415 sensor, the lens provides a 102° diagonal FOV, 85° horizontal FOV, and 45° vertical FOV.

Q: Is this an 8MP M12 lens?
A: Yes. The lens is specified for 8MP imaging and is designed for high-resolution camera modules using compatible 1/2.8″ sensors.

Q: What is the advantage of the F1.0 aperture?
A: The large F1.0 aperture delivers higher light throughput to the image sensor, benefiting low‑light and nighttime imaging where image brightness is critical.

Q: Is this lens a low distortion lens?
A: No. Its TV distortion sits below −12.5%, so designers should not position it as a low‑distortion lens. The product fits the wide‑angle‑lens category for use‑cases that prioritize broad scene coverage.

Q: Is this M12 lens a fisheye lens?
A: This lens features 102° diagonal FOV and notable negative distortion, yet these specs alone do not define a fisheye design. Designers should treat it mainly as a wide‑angle lens unless its optics are explicitly categorized as fisheye.

Q: Does this lens have an IR cut filter?
A: No. The specification states “Without IRCF,” meaning the lens itself does not include an integrated IR cut filter. This allows the camera system designer greater flexibility in configuring the overall optical filter system.

Q: Can this lens be used for low-light security cameras?
A: Yes. The F1.0 aperture and wide field of view make it suitable for security camera modules that require broad scene coverage and strong light-gathering capability in dim environments.
