Safety Precautions

For safe operation, never look directly at the sun or strong light sources through the lens, as this may cause vision damage or fire. Do not disassemble or modify the lens. Keep the lens away from children to prevent injury from accidental drops. Avoid leaving the lens in direct sunlight or high-temperature environments like cars, as this can damage internal components.

Maintenance and Care

Clean the lens surface with a blower or a dry cloth after removing dust. Never use organic solvents like thinner or benzine. Store the lens in a clean, well-ventilated area. If the lens is exposed to sudden temperature changes, condensation may form; allow the lens to acclimate to room temperature before use. Avoid touching the lens-camera interface contacts with your fingers to prevent malfunctions.
