Canon A-1 - Manual (Page 159)

MOTORIZED FILM WINDING
There remains one last mechanical operation
in the A-1 that could possibly distract your
attention from your subject; you have to
wind
the film. Canon has solved that
problem for you too. Both the miniaturized
Canon Power Winder A, originally designed
for the AE-1, and the Canon Motor Drive
MA, specially developed as a natural ex­
tension of the A-l’s AE possibilities, auto­
matically wind the film and recock the
shutter without your ever having to touch
the film advance lever, all even when you are
using the A-1 in an AE mode (except for
stopped-down AE).
The Motor Drive MA is a compact, high-
performance device employing Monolithic
IC and an electromagnetic clutch. It offers a
selection of three speed settings: H (max. 5
fps), L (max. 3.5 fps) and S (single frame).
With the Battery Pack MA, the unusually
high speed (H) is instimtly accessible for
those fast-breaking situations. For maximum
ease of operation, there is also a selection of
three shutter buttons depending on how the
camera is hand-held.
Both accessories stop automatically at the
end of the film at which time an LED glows
steadily to tell you that the roll is complet­
ed. They mount onto the A-1 with ease, and,
even when mounted, can simply be switched
off to wind the film manually.
