Make sure the lens and dust cap mount indexes are aligned when attaching the dust cap. ●● Contacts that are scratched, soiled, or have fingerprints on them may result in faulty connections or corrosion, which may lead to malfunctions. If the contacts get soiled, clean them with a soft cloth. ●● The lens mount has a rubber ring to improve dust-resistance and water-resistance performance. This rubber ring may cause friction marks to appear around the camera's lens mount, although this will have no effect on usage. ●● Rubber rings can be replaced at Canon Service Center.
