Pentax K1000 User Manual

RESISTANCE TO TEMPERATURE EXTREMES AND CHANGES
The temperature range at which your camera
will continue to function properly stretches
from 50 °C to - 20 °C. However, resistance to
cold could be hampered by oil which has
become dirty. Therefore, if the camera is to
operate at full efficiency in very cold
conditions, it must be overhauled and all
oil must be replaced.
Sudden changes in temperature will often
cause moisture to condense inside or outside
your camera. This is a possible source of rust,
which may be extremely damaging to the
mechanism. Fur t hermore, if the camera goes
from a warm temperature to a sub-freezing
one, and if tiny drops of moisture freeze,
fu r ther damage may be done by their
expansion.
Thus, sudden temperature changes should be
avoided
as much as possible. As a guide, a
temperature change
of 10 °C should be allowed
to take place gradually over a period of at
least 30 minutes . If this is not possible, keep'ing
the camera
in its case or bag will help somewhat
in
minimizing the effects of a rapid temperature
change.
Extremely low temperature reduces the
efficiency of the battery. Therefore, the camera
should
be protected against low temperature.
Put the batteries into the camera right before
shooting.
For extremely low temperature, use
new batteries.
