lites 011 A, 155A, 166A, 177 A, 188A, 199A,

When the Speed lite is charged and the shutter
button is pressed halfway, a green 11 and the
auto working aperture light up in the viewfinder
display. After the shutter is released, the AE-l
PROGRAM switches automatically to normal AE
photography until the pilot lamp and green 11
glow again.
Notes
1. Except when the shutter speed selector dial is
set to "B," the AE-1 PROGRAM automatically
switches to 1/ 60 sec. as soon as the Speed-
lite's pilot lamp and the green
(J
glow.
2. Since the AE-1 PROGRAM displays only full
apertures in the viewfinder, the aperture dis-
played may be one-half fl stop larger or
smaller than the auto working aperture set on
the flash ; the auto working aperture is the
effective aperture.
