Cleaning of the Camera
When you use your camera on a rainy day, or
at the beach, moisture and salt air adhere to it,
which can result in stains, rust, and corrosion.
Use a soft brush to rid the body of dust and
a dry, soft cloth for wiping.
Cleaning of the Lens
Use a blower with a rubbur ball to blow away dust
on the lens or brush lightly with a brush. Do
not touch the lens. If you should inadvertently get
a finger print on your lens, follow this procedure :
use a little pure alcohol or ether, if available, on
special lens tissue. Then wrap the tissue around
a wooden matchstick and wipe the lens in a cir
cular motion. . . lightly and systematically.
• In extremely cold areas, expose the camera to
the outer air only when in use. Put it back im
mediately after use. When using, expose the
camera gradually to the outer air to prevent
the lens from clouding.
