and 90 . Flash coverage of lenses as wide as 24mm is also possible by attaching the Wide
Adapter.
All of these units are like the 199A in that they automatically change the shutter speed to 1/60 sec. and set the
camera to the automatic flash aperture you have set. There are two on the 188A, 177A and 155A (f/2.8 and f/5.6,
ASA100) and one on the 133A, f/4. Used with the Wide Adapter, the 188A and 177A give flash coverage of
28mm lens field. For flash other than having its contact on the flash feet or if you want to set up multiple flash
units, you can use the PC terminal as well.
And since all of these units couple perfectly with the A-l's circuitry, they can be used with the
Power Winder A2/A for automatic flash continuous shooting. However, since Canon advises
multiple exposures mode in not recommended to work in continuous mode for most of the A
series models, I am not so sure whether it applies in the flash AE mode as well for
stroboscopic effect.

Note: Although rarely used today, flash bulbs will work with Canon A-1, AE-1, AE-1 Program etc cameras which
are using a horizontal traveled focal plane shutter design. If you are using type FP, MF or M flash bulbs, 1/30 second
is the fastest shutter speed you can use. Naturally, with flash bulbs there is no automatic flash operation. Also check
sync speed with flash bulbs for models: Canon AE-1, AE-1 Program.
Can the Canon A-1 or for that matter, all the A and T series SLR models interchangeable to use with all the A, G and T
series flash units ? With the exception of the T90, all of Canon's A-series and T-series as well as the New F-1, will
automatically set their X-sync with any A-series, T-series (except 300TL) and G-series (533G & 577G) of Canon
Speedlites. Some has their own respective dedicated function, for an instance, AE-1 Program will automatically reverts to
powerful but equally as reliable and automatic as the 199A are the Speedlites 188A,
177A, 155A and 133A.
