Maintaining your camera lenses involves regular cleaning with a lens cleaning solution and a microfiber cloth or lens pen, and using a blower to remove dust. Always use a lens cap on both ends when your lens is not in use. Store your lenses in a cool, dry place, preferably in a padded camera case or bag, and avoid exposing them to extreme temperatures. Regular professional check-ups can help identify and resolve any issues early, ensuring your lenses remain in optimal condition.
