Pre-Shooting Checks - Canon SPPEDLITE 577G Instructions Manual

PRE-SHOOTING CHECKS
I. Test Firing and Auto Shooting
Check
a) AUTO/MANU Switch
b) Pilot lamp
c) Auto Check Lamp
Now that all camera, lens and
flash settings have been made,
turn on the power switch on
Transistor Pack G. After the flash
reaches sufficient charge for firing,
the pilot lamp will glow and you
can take a flash picture anytime.
If you wish to check the flash and
whether the shooting distance is
correct, press the pilot lamp after
it glows. A flash should be fired. If
the auto check lamp next to the
pilot lamp lights up right after¬
wards for about two seconds, it
means that your shooting distance
will give correct exposure. If it
does not glow, either set the aper¬
ture selection switch to a better
position or move closer to your
subject. This method of checking
shooting distance is especially
helpful when the flash is tilted or
swung for bounce flash (p. 25).
* The auto check lamp tells you
whether you are close enough to
your subject but not whether you
are far enough away. Even if you
are too close to get a well-
exposed picture, it will still glow,
so always keep the shooting
ranges given on the back of the
flash in mind and double check
the lens' distance scale if you think
you might be too close.
II. Checking Viewfinder Infor¬
mation
The Canon New F-1, A-1, AE-1
PROGRAM, AL-1, AE-1 and AV-1

tion for fiash photography. You
can check it by pressing the
shutter button halfway after the
pilot lamp glows.
