Using the Lens Cap
Always keep the lens cap on the lens whenever you are not
using the camera. Always leave the lens cap on the lens
when the camera is turned off and the lens is retracted.
Attach the lens cap holder to the neck strap or the strap ring.
This protects against accidental loss of the lens cap.
IMPORTANT!
• Never turn on camera power with the lens cap affixed
to the lens.
