4. A void extremes of humidity and temperature. Keep your
camera out of direct sunlight, car trunks, and glove
compartments. Shooting outdoors in winter presents a
problem since batteries won’t function if they get too
cold. In cold weather, carry your camera under your
coat or jacket to keep the batteries warm. The tempera¬
tures at which this camera should function properly are
approx. 50®-10°C. Sudden changes in temperature
will often cause condensation of moisture inside or on
the outside of your camera. This might cause extremely
damaging rusting of mechanisms. Furthermore,
transferring the camera from a relatively warm to sub¬
freezing temperatures creates damaging ice or frost
Thus, sudden temperature changes should be avoided
as much as possible. As a guide, a temperature change
of 10®C should occur gradually over at least 30 min¬
utes. If this is not possible, keeping the camera In its
case or bag will help minimize the effects of a rapid
temperature change.
5. Vibration from traveling in a car, plane, or ship can
cause screws to loosen. To minimize this problem, line
the bottom of your camera bag with inch-thick (2.54 cm)
foam-rubber padding.
6. When mounting your camera on a tripod, make sure
the tripod screw is no longer than 5.5 mm (0.22 in.},
which is the depth of your camera's tripod socket A
longer screw might puncture the tripod socket, and
damage the camera.
7. Do not place the camera with the zoom lens down with¬
out turning the main switch off; otherwise, the zooming
mechanism may be seriously damaged.
