Introduction
The Canon Speedlite 188A is an automatic,
electronic, flash unit for hot-shoe attach¬
ment on the Canon A-series SLR cameras
such as AE-1 PROGRAM or A-1, and F-1
The speedlite mounts onto the accessory
shoe of the cameras lor hot-shoe attach¬
ment
On the A-1. AE-1 PROGRAM, and AE-1.
the 188A will set both the shutter speed
the aperture for the cameras set normally
for automatic exposure
For the F-1. the
188A will set only the shutter speed or lens
aperture as well depending on the exposure
mode the camera is set for. For the AL-1,
AV-1 and AT-1, the flash will set the shut¬
ter speed automatically while the aperture is
set manually
When the 188A is used with the AE-1
PROGRAM, a blitz "[J]" mark lights up In
the viewfinder when the flash is charged.
After the shutter is released, the same dis¬
play flashes on and off to indicate there
was sufficient illumination for the shooting
distance. Thus you can concentrate on
shooting

You
never have to take your eye away from the
viewfinder.
For the AE-1
PROGRAM as well as for
other A-series SLRs and the F-1, a unique
average light measuring system ensures at¬
taining better overall exposure.
Another feature of the 188A is that while
you are waiting for the flash to recycle, the
camera's normal automatic exposure func¬
tion is retained and you can shoot using ex¬
isting light Of course, for insufficient light
slow shutter speed is required and long ex¬
posures may be suitable only when there is
no motion to be stopped
