Film Advance And Shutter Release - Canon A-1 Instructions Manual

Film Advance and Shutter Release
.A.
t th e base of the film advance lever is the
main switch of the camera. When it is at the
"L" {LOCK)
setting, all active circuits are
turned off and the shutter button is locked
to prevent unintentional shutter release. This
switch should always be in the "L" position
to prevent battery consumption and film
wastage when the camera is not in use, such
as when it is in a camera case.
When Lhe main switch is set at "A", the
shutler button can be operated. The shutter
button serves to activate both the AE meter
and shutter operation. Since it is electro-
m agnetic, it requ ires only gen tle pressure for
both a very smooth shutler release as well as
immedia te meter response when shooting in
quick succession. Pi:essing the shutter button
lightly only halfway gives a meter reading
preview inside the viewfinder. When you
press it gently all the way, the mirror flips
up, the diaphragm closes down and the
-22-
shutter releases. After shutter release, the
mirror and diaphragm automatically reset
and the film advance lever is ready to be
advanced.
With the l ip of your thumb, lightly push the
film advance
l~ver
away from the camera
body to its 30 stand-off position. Now it
can be easily operated with the tip of your
thumb. Push it a ll the way to the right in a
single, short t20° throw to wind the rilm,
cock the shutter and prepare the diaphragm
and mirror for the next shutter re lease all in
one motion.
()r
you can advance the lever in
several short strokes. Each winding will also
advance the number in th e frame counter,
indicating the number o f pictures taken.
