• Body Cleaning: Clean the lens barrel and mount with a soft, dry cloth. Do not use organic solvents or strong cleaning agents.
• Environmental Precautions: The lens is not weather-sealed. Avoid using it in environments with high humidity, heavy rain, or extreme temperatures to prevent internal damage.

6. Troubleshooting

If you encounter any issues with your VILTROX AF 28mm F4.5 FE lens, please refer to the following common troubleshooting steps:

• Autofocus Issues: If the autofocus is slow, inconsistent, or fails to lock onto subjects, ensure the lens firmware is up to date. Check your camera's autofocus mode and area settings. In low-light conditions, autofocus performance may be reduced.
• Image Quality Concerns: If images appear soft, blurry, or exhibit unusual artifacts, verify that the lens elements are clean and free from smudges or dust. Ensure the lens is securely mounted to the camera body. Check your camera's ISO, shutter speed, and aperture settings for appropriate exposure.
• Lens Not Recognized by Camera: If the camera does not detect the lens, power off the camera, detach the lens, and then re-attach it, ensuring it clicks firmly into place. Clean the electronic contacts on both the lens mount and the camera body with a clean, dry cloth to ensure proper communication.
• Unusual Noises: If the lens produces unusual noises during operation, power off the camera and remove the lens. Inspect for any visible obstructions or damage. If the issue persists, contact VILTROX customer support.
