To attach it properly, align the lens mount index
and the  index of the dust cap as shown in
the diagram, and turn clockwise. To remove it,
reverse the order.
The lens mount has a rubber ring for enhanced
dust- and water-resistance. The rubber ring may
cause slight abrasions around the camera's lens
mount, but this will not cause any problems. If the
rubber ring becomes worn, it is replaceable by a
Canon Service Center at cost.
Attaching the strap
Thread the end of the strap through the strap
mount on the lens and then back through the
clasp on the strap. Pull the strap tight and check
that there is no slack in the clasp.
