Canon AT 1 - Manual (Page 111)

Canon Power Winder A
The Canon Power Winder A is an auto­
matic film winder. It can be attached to
any Canon AT-1 directly, without any other
accessory or attachment. When you attach the
Power Winder A to the Canon AT-1 and press
the shutter button, the film will be im­
mediately wound after being exposed.
Furthermore, with the Power Winder A you
can catch subjects’ movements and changing
expressions because you are able to take
continuous or single frame photography at
your pleasure. Continuous photography at up
to two frames per second is performed just
by keeping the camera's shutter button
depressed. Shutter speeds from 1/60 to
1/1000 seconds couple in continuous photo­
graphy. While in single frame photography,
any shutter speed can be used. This is simply
done by lifting your finger off the camera's
shutter button.
The Canon AT-1 and Power Winder A
form a compact, lightweight package that is as
portable as a manual advance camera, and
much more convenient.
