AE-1 Viewfinder Information
Once the flash is charged and the pilot
lamp glows, the meter needle will swing
to the aperture pre-selected on the 155A. If
the pre-selected aperture is outside the aper¬
ture range of the lens, either the under-ex¬
posure lamp blinks or the ^ meter needle
enters the overexposure mark. In these cases,
change the; aperture setting on the 155A.
Since the meter needle does not swing to the
flash-selected
aperture
until
the flash is
charged, you could tell the flash was ready
for firing simply by looking into the view¬
finder. However, since it is possible that
the flash-selected aperture might be the same
as that chosen by the camera for non-flash
AE photography, it is advisable to make sure
the pilot lamp is glowing before firing.
*
When you are performing normal AE
photography during the flash interval,
there may be a very rare occurrence
where the pilot lamp will light up while
the shutter is in operation if the flash is
charged. If this should happen, the frame
will be improperly exposed.
Precautions in Automatic Flash Photography
In some cases AE flash photography may
not be suited to your subject. If, for instance,
your main subject is small while the back¬
ground is dark or distant or if the background
is whitish or bright with strong reflections,
AE flash exposure may be affected by the
background, causing under- or overexposure.
This can be avoided by switching to manual
flash control.
If using a self-timer, do not press the shutter
release until the pilot lamp glows.
When the shooting distance is less than one
meter, the difference between the optical
axes of the lens and the flash may result
