3. Setup and Installation
The MX-B079 lens is designed for straightforward installation onto compatible Mobotix camera modules. Ensure the camera is powered off before proceeding with installation.
- Prepare the Camera Module: Carefully remove any existing lens or protective cap from the camera's sensor module. Handle the sensor area with extreme care to avoid dust or damage.
- Attach the Lens: Align the threads of the MX-B079 lens with the lens mount on the camera module. Gently screw the lens into place clockwise until it is finger-tight. Do not overtighten.
- Secure the Lens: Some camera models may have a locking mechanism or set screw to secure the lens. Refer to your specific camera's manual for details on securing the lens to prevent accidental rotation or detachment.
- Power On and Test: Once the lens is securely attached, power on the camera. Access the camera's web interface or monitoring software to verify the image quality and field of view. Adjust the focus if necessary, though fixed lenses typically have a broad depth of field.
For optimal performance, ensure the lens is clean and free from smudges or dust before and after installation.
4. Operating Characteristics
The MX-B079 is a fixed lens, meaning its focal length and aperture are constant. Its operational characteristics are primarily defined by its optical properties:
- Field of View: With a 6MP sensor, the lens provides a 45° horizontal and 34° vertical field of view. This makes it suitable for general surveillance applications where a standard perspective is required.
- Depth of Field: Due to its fixed aperture and focal length, the lens offers a consistent depth of field. Objects within a certain range will appear in focus without manual adjustment.
- Low Light Performance: The f/1.8 aperture allows for good light gathering capabilities, contributing to better image quality in low-light conditions compared to lenses with higher f-numbers.

5. Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your MX-B079 lens.
- Cleaning the Lens: Use a soft, lint-free microfiber cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens).
- Dust Removal: Use a blower brush or compressed air (designed for electronics) to remove dust particles from the lens surface. Avoid wiping dry dust, as it can scratch the lens.
- Storage: When not in use, store the lens in a clean, dry environment, ideally with lens caps attached to protect the optical surfaces from dust and scratches.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or strong chemicals on the lens or its housing, as these can damage the coatings or material.
6. Troubleshooting
If you encounter issues with your MX-B079 lens, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blurry or Out-of-Focus Image | Lens not fully screwed in; dirty lens surface; camera sensor issue. | Ensure lens is securely attached. Clean the lens carefully. Check camera settings or consult camera manual. |
| Dark Spots or Smudges on Image | Dust or dirt on lens surface or camera sensor. | Clean the lens. If spots persist, carefully inspect and clean the camera sensor (refer to camera manual). |
| Image Distortion | Incorrect lens for camera model; software settings. | Verify lens compatibility with your specific Mobotix camera model. Check camera's image correction settings. |
| No Image | Lens not installed; camera not powered; cable issue. | Ensure lens is installed correctly. Check camera power and network connections. |
