A-TTL Automatic Mode:
The Speedlite 300EZ features the A (Ad-
vanced)-TTL mode which can be used
under conditions ranging from total dark¬
ness to fill-in flash.
Flash
output
is
controlled
by
directly
measuring the light coming through the lens
and reflected from the film surface, using
the
sensor
inside
the
camera
body.
Moreover, this A-TTL mode balances the ex¬
posure
between
the
main
subject
il¬
luminated by the flash and the background
in ambient light to prevent unnatural effects.
The setting for each shooting mode is
slightly different so please read the
following carefully.
The camera-shake warning does not
sound when the flash is turned on.
When the camera is set to the depth-of-
field AE mode with the flash ON, the
mode is automatically switched to the
program AE mode.
