AE Flash Photography
(Full Auto-
flash Photography)
There are seven special automatic flash units,
the Canon Speetllitt:s 577G, 533G, 199A,
188A, 177A, 155A and 133A, which make
AE flash photography possible with the
A-1. Just slip the Speedlite 577G's or
533G's sensor unit or the 199A, 188A,
l 77A, 155A or 133A into the accessory
shoe, switch on the flash, focus and shoot.
It does not matter whether the AE mode
selector is set to Av or Tv. Except for
"B", whatever the shutter speed set, as soon
as the pilot lamp or the Speedlite comes
on, the A-1 switches to the X synchroniza-
tion speed of 1/60 sec. - automa tically.
The speedlite's sensor controls the light
output for p erfect automatic exposure
within auto working ranges. And just as
automatically will the camera switch back
to the shutter speed ac tually set on the dial
as
soon as the pilot lamps goes out. The
viewfintler offers you full i11fur111atiun
needed for tlash photography. Moreover,
when the main switch of the Speedlite is
turned off, the nash c ircuitry is completely
cut off and the A-1 switches over to function
as an AE control camera without detaching
the Specdlite or sensor uni t from the acces-
sory shoe.
