Speedlites - Canon AE-1 PROGRAM Instructions Manual

Speedlites 011A, l55A, l66A, l77A, l88A, 199A, 533G and 577G
For the easiest possible flash photography with
the AE-1 PROGRAM, Canon offers nine Speed-
lites. With an FD lens set to the "A" mark, the
shutter speed switches to 1/ 60 sec. and the
aperture to the auto aperture set on the flash
automatically when the pilot lamp glows. After
shutter release, the camera switches automatic-
ally to normal AE photography until the pilot
lamp glows again.
Canon ' s most powerful Speedlites, the 577G
and 533G each use a quick-release grip and a
separate sensor which , seated in the camera's
accessory shoe, ensures correct exposure even
when the flash head is tilted or swung . The
A-series Speed lites slide directly into the acces -
sory shoe.
When using any of these Speed lites, a green LED
display lights up in the viewfinder of the AE-1
79
PROGRAM the moment the flash unit is charged .
And, when using the Speed lite 188A or 1 66A,
that same LED display will flash on and off for
two seconds after you take a picture to confirm
correct exposure. No other flash units offer these
features. You can also switch to manual flash
photography with six out of these eight Speed-
lites.
When you are finished using the flash , you can
shoot normally while the flash or sensor is still
mounted simply by turning off the flash unit's
main switch .
With seven units available, you have a wide
range of features to choose from. The table on
page 80 and 81 lists some of the most impor-
tant.
