Shooting In Very Low Temperatures - Canon AE-1 PROGRAM Instructions Manual

24. Shooting in Very Low Temperatures
When you use the AE-l PROGRAM in tem-
peratures below O° C (32 ° Fl, there are two things
you should keep in mind. First, battery power
may decrease or fail altogether. Second, extreme
temperature changes may damage the camera
unless certain precautions are taken.
Try to remember the following:

1. Load a new battery, and keep the camera
warm until you are ready to shoot. Try to
finish the shooting session as quickly as
possible. If you must shoot for a long time,
carry a spare battery. Alternate the two bat-
teries, keeping the one that is not in use warm .
Do not throw the original battery away. That it
does not perform well in the cold does not
necessarily mean that it will not work normally
again in warmer temperatures. An optional
accessory, the Canon External Battery Pack A,
is the most reliable power source for uninter-
rupted shooting in cold weather. .
2 . Condensation forming on a camera and lens
taken from cold outside temperatures into a
warm room may cause corrosion . To avoid
this, while still outdoors place the camera in a
plastic bag. Then seal the bag and take it
indoors. Leave the camera in the bag until it
gradually reaches room temperature. Gener-
ally, this takes about one-half hour.
