6. Maintenance

• Cleaning the Lens Surface: Use a soft, clean microfiber cloth specifically designed for optical lenses. For stubborn smudges, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
• Cleaning the Lens Body: Wipe the lens body with a soft, dry cloth. Do not use organic solvents like paint thinner or benzene.
• Storage: When not in use, attach the front and rear lens caps and store the lens in a dry, well-ventilated area, away from direct sunlight and high temperatures. If storing for extended periods, place it in a sealed container with desiccant to prevent mold and mildew.
