Maintenance

Cleaning the lens

1 Apply a non-abrasive camera lens cleaner to a soft, dry cloth.

Avoid using an excessive amount of cleaner, and don’t apply the cleaner directly to the lens. Abrasive cleaners, solvents or other harsh

chemicals might scratch the lens.

2 Lightly wipe the cleaning cloth over the lens in a circular motion.
