Attaching a Strap
To attach a strap (whether the supplied strap or one that has been purchased
separately), follow the steps below.
• If the strap is not attached correctly, the lens could fall, causing injury.
• Use a lens strap when carrying the camera with the lens attached. Using a
strap attached to the camera alone could damage the strap or the mounts on
the camera or lens, causing the camera or lens to fall.
